Firefox 3.6 has some new features, like Personas being part of the browser 
itself.  As such, we have taken this opportunity to review and update our 
privacy policy.  Privacy and data protection are important issues to the people 
of Mozilla.  So we are looking at all the terms of this policy and thinking 
about how to best use our privacy policy to benefit users.  This means you 
should expect more significant changes in the future.  For example, we are 
considering ways to significantly shorten and simplify this policy.  If you 
would like to get involved in the privacy efforts at Mozilla, please feel free 
to contact me.

You can view the complete set of changes since the April 2009 version at this 
page:  http://people.mozilla.org/~cwang/Mozilla-Privacy-Policy-3-6-diff.pdf  

Some changes to note in particular:  
*looked at each of the hypertext links to ensure they were accurate
and appropriate.  As a result, we removed a few and rerouted a few;
*added provisions to address how Personas will work;
*moved pre-3.0 discussions to the end of the document since this
affects a subgroup of users and added to the length and complexity by having it 
"inline";
*included the process for reviewing and correcting your data;
*included language re some of the steps we take around security. 

Here is the policy:

Mozilla Firefox Privacy Policy
Last Updated: January 20, 2010
This privacy policy explains how Mozilla Corporation (“Mozilla”), a 
wholly-owned subsidiary of the non-profit Mozilla Foundation, collects and uses 
information about users of the official Mozilla Firefox® web browser 
(“Firefox”) for computers (desktops, laptops, netbooks).  It does not apply to 
other Mozilla websites, products or services.  In particular, Firefox for 
Mobile has its own separate privacy policy at 
http://www.mozilla.com/en-US/legal/privacy/firefox/mobile/ because the features 
are slightly different..  
Types of Information
As with most Internet web browsers, Firefox sends certain information to the 
websites that you visit.  This information falls into the following categories:
“Personal Information” is information that you provide to us that personally 
identifies you, such as your name, phone number, or email address. Except as 
described below, Mozilla does not collect or require end-users of Firefox to 
provide Personal Information.
“Non-Personal Information” is information that cannot be directly associated 
with a specific person or entity.  Non-Personal Information includes but is not 
limited to your computer’s configuration and the version of Firefox you use.
“Potentially Personal Information” is information that is Non-Personal 
Information in and of itself but that could be used in conjunction with other 
information to personally identify you.  For example, Uniform Resource Locators 
(“URLs”) (the addresses of web pages) or Internet Protocol (“IP”) addresses 
(the addresses of computers on the Internet), which are Non-Personal 
Information in and of themselves, could be Personal Information when combined 
with Internet service provider (“ISP”) records. 
“Aggregate Data” is information that is recorded about users and collected into 
groups so that it no longer reflects or references an individually identifiable 
user.
Cookies
A cookie is a small string of information that a website stores on your 
computer and that web browsers make available to that website each time you 
return.  Firefox stores cookies on your computer when requested to do so by 
websites.  A website uses cookies to help identify and track visitors, the use 
of the website, and visitors’ website access preferences across multiple 
requests and visits. It is possible to include Personal Information, or 
references to such information, in cookies, thereby enabling websites to track 
the online movements of particular individuals. To prevent Firefox from sending 
cookies to specific websites, configure Firefox to prompt you when a website 
wants to set a cookie.  To prevent Firefox from sending cookies to any website, 
configure it to disable cookies.  An article in our Firefox Knowledge Base 
gives you information about changing these preferences. 
Information Firefox Sends to Websites
Like most web browsers, Firefox sends information to the websites you visit, 
including Non-Personal Information of the type that web browsers typically make 
available, such as the type of browser you are using, your language preference, 
the referring site.  This information may be logged by the websites you visit.  
What information is logged and how that information is used depends on the 
policies of each of the websites you visit.
Each website determines its own privacy practices for the distribution and use 
of this Non-Personal Information and Potentially Personal Information.  If you 
are concerned about how a website will use this information, check out its 
privacy policy.  To find out more about how Mozilla uses this information on 
its own websites, see the Mozilla Privacy Policy.
Interactive Product Features
Add-ons Features.  One thing that makes Firefox so flexible is the ability for 
you to add various add-ons, extensions, and themes to Firefox, thereby creating 
a custom browser that fits your needs.  The following features show how Firefox 
3.x provides both the ability to obtain additional add-ons easily and to 
protect against potentially harmful add-ons. 
Get Add-ons Feature and Add-Ons Update.  Firefox 3.x offers a Get Add-ons 
Feature and update service.  The Get Add-ons Feature creates a list of 
recommended add-ons and extensions to try.  You access this recommended list by 
clicking on the “Get Add-ons” tab from the Firefox Add-ons Manager. To display 
the recommended list, Firefox sends certain information to Mozilla, including 
the type of computer and version of Firefox you are using as well as your IP 
address and any cookies set bythe Add-Ons webpage, but Firefox 3.x does not 
collect any Personal Information as part of a download from the Firefox Add-Ons 
Manager.  Add-Ons Update collects the same information.
Automated Update Service.  Firefox’s automatic update feature periodically 
checks to see if an updated version of Firefox and installed add-ons are 
available from Mozilla.  
Firefox. This feature sends Non-Personal Information to Mozilla, including the 
version of Firefox you are using, build ID and target, update channel, your 
operating system, and your language preference. This feature also sends 
Potentially Personal Information to Mozilla in the form of your IP address and 
a cookie that contains a unique numeric value to distinguish individual Firefox 
installs.  Mozilla uses this information to provide you with updated versions 
of Firefox and to understand the usage patterns of Firefox users.  We use this 
information to improve our products and services and to support decision making 
regarding feature and capacity planning. 
Firefox 3.x does not collect or track any Personal Information or any 
information about the websites you visit, and Mozilla does not release the raw 
information we obtain from these Firefox 3.x features to the public.  We may 
release reports containing Aggregate Data so that our global community can make 
better product and design decisions.  To prevent Mozilla from obtaining this 
information, you can turn this feature off in Firefox’s preferences.  An 
article in our Firefox Knowledge Base gives you information about changing your 
preferences. 
Blocklist Feature.  Firefox 3.x also offers a Blocklist feature. With this 
feature, once a day Firefox does a regularly scheduled, automatic check to see 
if you have any harmful add-ons or plug-ins installed.  If so, this feature 
disables add-ons or plug-ins that Mozilla has determined contain known 
vulnerabilities or major user facing issues or fatal bugs (e.g., client crashes 
on startup or something causing an endless loop of unusability).  You may view 
the current list of Blocklisted items.  This feature sends Non-Personal 
Information to Mozilla, including the version of Firefox you are using, 
operating system version, build ID and target, update channel, and your 
language preference. This feature also sends Potentially Personal Information 
to Mozilla in the form of your IP address and a cookie. In addition, Mozilla 
also uses this feature to analyze Firefox usage patterns so we may improve our 
products and services, including planning features and capacity.  Currently 
there is no basic user interface to disable the Blocklist feature.  An article 
in our Firefox Knowledge Base explains how you may disable the Blocklist 
feature.  Disabling the Blocklist feature is not recommended as it may result 
in using extensions know to be untrustworthy.
Crash-Reporting Feature.  Firefox has a crash-reporting feature that sends a 
report to Mozilla when Firefox crashes.  Mozilla uses the information in the 
crash reports to diagnose and correct the problems in Firefox that caused the 
crash.  Though this feature starts automatically after Firefox crashes, it does 
not send information to Mozilla until you explicitly authorize it to do so.  By 
default, this feature sends a variety of Non-Personal Information to Mozilla, 
including the stack trace (a detailed description of which parts of the Firefox 
code were active at the time of the crash) and the type of computer you are 
using.  Additional information is collected by the crash reporting feature. 
Which crash reporting feature is used and what additional information collected 
by Firefox depends on which version of Firefox you’re using.  For pre-3.x 
versions of Firefox, please see the end of this privacy policy.
Firefox 3.0 to present.  For the current versions of Firefox, “Firefox Crash 
Reporter” is Firefox’s crash reporting feature.  With this feature, you have 
the option to include Personal Information (including your email address), 
Potentially Personal Information (including your IP address and the URL of the 
site you were visiting when Firefox crashed), and a comment.  Firefox Crash 
Reporter also sends a list of all add-ons that you were using at the time of 
the crash, the time since (i) the last crash, (ii) the last install, and (iii) 
the start-up of the program.  For Firefox 3.0.0 – 3.0.5, Firefox Crash Reporter 
also collects Potentially Personal Information to Mozilla in the form of a 
unique alphanumeric value to distinguish individual Firefox installs.  This 
value is not assigned to users of Firefox 3.0.6 and subsequent versions.  
Mozilla only makes Non-Personal Information (i.e., generic information about 
your computer, the stack trace, and any comment given by the user) available in 
the public reports available online at http://crash-stats.mozilla.com/. 
To safeguard your privacy, Mozilla’s policy is to make Personal Information, 
such as your name and email address, and Potentially Personal Information, such 
are the URL of the site you last visited, only available to its employees, 
contractors, and selected contributors who signed confidentiality agreements 
that prohibit them from using or disclosing such information other than for 
approved Mozilla purposes.
Location-Aware Feature.  Beginning with Firefox 3.5, Firefox offers a 
Location-Aware Feature, parts of which may be provided by third-party service 
providers 
You Elect to Use the Location-Aware Feature.  This feature remains inoperative 
until you visit a website that requests your location and you choose to opt in 
to the feature.  If you elect not to, nothing happens.  Each time you visit 
such a website, Firefox asks you if you want it to provide the site with your 
current location.  Additionally, you may elect to have Firefox remember your 
choice to allow or not allow the feature for each site. Any such election is 
domain specific. You are able to opt out at any time of having Firefox remember 
your choice, just like any other preference setting.  
What Information Firefox Collects. If you choose to allow it, the Firefox 
Location-Aware Feature first collects one or more of the following relevant 
location markers: (i) location provided by a GPS device built into or attached 
to your computer or device and/or geolocation services provided by the 
operating system; (ii) the wifi routers closest to you; (iii) cell ids of the 
cell towers closest to you; (iv) the signal strength of nearby wireless access 
points and/or cellular phone towers; and/or (v) your computer or device’s IP 
address.  Next, it attempts to determine your location using these location 
markers.  Any information Firefox uses, receives or sends as part of this 
Location-Aware Feature is not received by any Mozilla servers or by Mozilla.  
Firefox does not track or remember your location.   Firefox does remember a 
random client identifier, the temporary ID assigned by our third party provider 
to process your request, for two weeks.
What Information Third Parties Receive & Provide.  If necessary, Firefox sends 
the information above, except any GPS information and/or geolocation data 
provided by the operating system, plus your user agent information (e.g, 
version of Firefox you’re using), along with a temporary client identifier, to 
its third party service provider(s) capable of deriving a physical location 
from the information Firefox has collected (e.g., convert a set of WiFi signal 
strengths into latitude and longitude).  This information is sent over an 
encrypted connection. The connection between Firefox and the service provider 
does not use any cookies. Neither the domain name nor the URL of the site 
you’re visiting are sent to our service providers.  Our providers estimate your 
location and return it to Firefox.  Firefox provides your location information 
to the webpage that made the request.  For any information the webpage sends 
back to the website, please see that website’s privacy policy. 
How Third Parties Providers Use the Information Received. Our policy is to 
require third-party providers to enter licensing agreements with Mozilla, which 
prohibit them from releasing Personal or Potentially Personal Information to 
the public.  We only permit our third party providers to use this information 
in conjunction with the service(s) they are providing to us.  They are required 
to ensure that any information collected on our behalf is anonymized and 
aggregated before they are permitted to use such information to develop new 
features or products and services, or to improve the overall quality of any of 
their products and services.  For example, this means that they are required to 
ensure that your IP address and unique identifier of your client will be 
stripped out before being used by any of our third party provider’s other 
products or features.  For more information, please see our by third-party 
service providers.
Third Party Websites.  Please carefully consider any website's privacy 
practices before agreeing to share your location with that website.
·       Requesting Websites. For any information the webpage sends back to the 
website, please see that website’s privacy policy.

·       Location-Aware Service Providers.  In addition, our service providers 
have their own privacy policy.

·       ISP and Mobile Carrier.  All requests for your location must be sent 
through your Internet service provider or mobile carrier network and your 
service provider or carrier may have access to the request. For information 
regarding your service provider's or carrier's treatment of your information, 
please consult their privacy policies. 

Personas Feature.  Firefox’s Personas feature is a theme that lets you 
personalize the look of your browser.  
Personal Information
Applying Personas.  When you apply a Personas to your browser, Mozilla collects 
your IP address, the date and time you applied the Personas design to your 
browser, and the url you used to make the application as well as the url you 
were visiting immediately before that (known as the “referrer” url).  
Creating a Custom Persona.  If you are creating a Custom Persona for your own 
use, Mozilla does not collect any Personal Information.
Contributing a Design to the Personas Gallery.  The Personas gallery is where 
you can browse all the available designs.  If you contribute a design or image 
(each a “Persona Design”) to the Personas gallery, Mozilla collects the 
following Personal Information: (1) your user name and (2) your email address.  
Your user name will be used to attribute your Persona Design to you and will be 
publicly available on the Personas gallery.  You do not have to provide your 
real name; you can use a nickname or avatar.  Mozilla will not make your email 
address publicly available or share it with any third parties other than 
Mozilla’s service providers.  Mozilla will use your email address only to 
contact you regarding your design or to provide any additional information that 
you elect or opt in to receive.
Personas’ Interactive Product Features
After you have selected your Personas Design, it is stored on your computer.  
Once per day Personas checks to see if your selected Persona Design has been 
updated.  This feature sends the same information that web browsers typically 
transfer with any HTTP requests including user agent and your IP address. 
We use this information to improve our products and services and to support 
decision making regarding feature and capacity planning.  Mozilla is an open 
organization that believes in sharing as much information as possible about its 
products, its operations, and its associations. Accordingly, we may release 
public reports containing Aggregate Data so that our global community and 
Personas partners may make better product and design decisions.  For example, 
we think it is good for  users of Personas to know which are the most popular 
Persona Designs and Personas designers to know how many times their Persona 
Design was downloaded.  
Report Broken Website Feature.  Firefox’s Report Broken Website feature lets 
you notify Mozilla when a website you visit improperly displays or incorrectly 
functions.  The feature sends the URL of the broken website to Mozilla.  You 
may also choose to send your email address and a description of the problem.  
This feature also sends a your IP address and a variety of Non-Personal 
Information to Mozilla, including but not limited to the version of Firefox you 
are using and your language preference.  Except for your email and IP address, 
Mozilla makes all of this information public.  This feature does not send 
information to Mozilla until you explicitly authorize Firefox to do so.  To 
prevent this public release of Personal and Potentially Personal Information, 
don’t report a website if the website’s URL contains your Personal and 
Potentially Personal Information, and don’t include Personal Information in 
your description of the problem.  To prevent the release of any information, 
don’t use this feature to report a broken website.
Report Web Forgery Feature.  Firefox’s Report Web Forgery feature lets you 
report suspected web forgeries to Mozilla’s third party service provider(s) for 
the web forgery protection feature when you encounter a suspected malicious 
“phishing” or fraudulent website that is impersonating a legitimate website.  
This feature sends your comments about the suspected fraudulent website to our 
third-party provider(s), as well as the same information that the browser sends 
when you visit a website.  Our policy is to require each of our third-party 
providers to enter into written agreements with Mozilla that prohibit them from 
releasing Potentially Personal Information to the public.  Our policy is to 
only permit these third party providers to use this information in conjunction 
with the web forgery protection service they are providing.  In addition, we 
require each third-party provider to maintain its own privacy policy that is 
linked to the online form where you report a potential web forgery.  To prevent 
the third party provider from obtaining this information, don’t use this 
feature to report a web forgery.  (Also see “Protection Against Suspected 
Forgery and Attack Sites Features” below.) 
Security
Mozilla is committed to protecting your personal information from unauthorized 
access, alteration, disclosure, or destruction. We undertake a range of 
security measures including physical access restraints, technical security 
monitoring, and internal security reviews of the environment.   We also have 
polices in place to prohibit employees from viewing personal information 
without business justification.  Additionally, it is our policy to ensure that 
Mozilla employees and contractors are bound by confidentiality obligations.
Beginning with Firefox 2.0, Mozilla has additional security features, some of 
which are provided by third party service providers.  
The security features available depend on the version of Firefox you are using. 
 Please see the ened of this privacy policy for older versions of Firefox.
Firefox 3.0 to 3.x
Secure Website Certificate Verification.  When you visit a secure website, 
Firefox will check with the certificate provider to validate that website’s 
certificate.  Firefox sends only the certificate identification to the 
certificate provider, not the exact URL you are visiting.  If the certificate 
is not valid, you will receive an error page that states the certificate was 
revoked and you will not be able to access that website.  The technical name 
for this process is OCSP or On-line Certificate Status Protocol.  You may 
completely turn off the secure website certificate verification feature in 
Firefox’s preferences under the encryption tab.  If you do this, none of the 
information discussed here will be sent to any third party certificate 
provider.  An article in our Firefox Knowledge Base gives you information about 
changing your preferences.  
Protection Against Suspected Forgery and Attack Sites Features.  The Firefox 
forgery and attack protection feature displays a warning if the website you are 
visiting is suspected of impersonating a legitimate website (commonly referred 
to as a phishing or forgery website) or a site that infiltrates or damages a 
computer system without your informed consent, including, without limitation, 
any computer viruses, worms, trojan horses, spyware, computer contaminant 
and/or other malicious and unwanted software (commonly called an attack site or 
malware).  By default, Firefox checks the web pages that you visit against a 
blacklist that is downloaded to your hard drive at regularly scheduled 
intervals (e.g., approximately twice per hour), the rate of frequency may 
change from time to time.  The blacklist does not include the full URL of each 
suspicious site. Instead, each URL is hashed (obscured so it can't be read) and 
then broken into portions. Only a portion of each hashed URL is included on the 
blacklist on your hard drive. If there is a match, Firefox will check with its 
third party provider to ensure that the website is still on the blacklist.  The 
information sent between Firefox and its third party provider(s) are hashed 
URLs.  In fact, multiple hashed URLs are sent with the real hash so that the 
third party provider(s) will not know what site you are visiting.  If there is 
a match, Firefox displays either a “Reported Web Forgery” or “Reported Attack 
Site” alert, as applicable.  
You may completely turn off the forgery and/or attack site protection features 
in Firefox’s preferences.  If you do this, none of the information discussed 
here will be downloaded to your hard drive or sent to any third party service 
provider.  An article in our Firefox Knowledge Base gives you information about 
changing your preferences.  
Each time Firefox checks in with a third party provider to download a new 
blacklist, Non-Personal Information and Potentially Personal Information, such 
as the information that the browser sends every time you visit a website as 
well as the version number of the blacklist on your system, is sent to a third 
party provider.  In order to safeguard your privacy, Firefox will not transmit 
the complete URL of web pages that you visit to anyone other than Mozilla and 
its service providers.  While it is possible that a third party service 
provider may determine the actual URL from the hashed URL sent, Mozilla’s 
policy is to require its third party service providers to enter into a written 
agreement with Mozilla not to use any data or other information about or from 
users of Firefox  for purposes other than to provide and maintain their 
service.  In addition, Mozilla’s policy is to prohibit these third party 
service providers from correlating any Firefox user data with any other data 
collected through other products, services or web properties of that provider.  
These third party service providers may post about additional notices regarding 
their applicable privacy policies.  (For example, see Google Safe Browsing 
Service in Mozilla Firefox Version 3.)
Please note that we’re not yelling at you in this paragraph.  Our lawyers have 
advised us that we need to make sure this information is conspicuous so you’ll 
read it.  The forgery and attack site protection feature is provided “as is” 
and for your information as advice and guidance only.  Mozilla and its 
contributors, licensors and partners do not guarantee that these protection 
features will prevent you from being deceived by a malicious website and we 
strongly recommend that you continue to be vigilant while online, particularly 
when following links sent to you in e-mail.  
Legally Required Disclosures
Mozilla may be required to disclose information to the government or others.  
This may happen if we receive a valid search warrant, subpoena, court order, or 
other legal mandate.  For example, the DMCA framework (specifically in Section 
512(h)) contains an expedited subpoena process for copyright holders to request 
and receive information service providers have regarding the identity of 
alleged copyright infringers.  
Other Disclosures
In certain other limited situations, Mozilla may disclose your Personal 
Information, such as when necessary to protect our websites and operations 
(e.g., against attacks); to protect the rights, privacy, safety, or property of 
Mozilla or its  users; to enforce our terms of service; and to pursue available 
legal remedies. Additionally, Mozilla may need to transfer Personal Information 
to an affiliate or successor in the event of a change of our corporate 
structure or status, such as in the event of a restructuring, sale, or 
bankruptcy.
Service Providers
We work with third parties who provide services (like companies that help us 
determine the number of users of Firefox and various features of Firefox) and 
content delivery networks and other services of an administrative nature.  We 
may share Personal Information about you with such third parties for the 
purpose of enabling these third parties to provide such services.
Transfer of Data to the U.S.
Mozilla is a global organization and operates in different countries. Privacy 
laws and common practices vary from country to country. Some countries may 
provide for less legal protection of your personal data; others may provide 
more legal protection. By using Firefox, you consent to the transfer of the 
information collected, as outlined by this Policy, to Mozilla or its third 
party service providers in the United States, the Netherlands, and other places 
where our distributed, third party content delivery network exists (which is in 
several countries around the world), which countries may provide a lesser level 
of data security than in your country of residence.
Data Retention
We will retain any information collected for the period necessary to fulfill 
the purposes outlined in this Policy unless a longer retention period is 
required by law and/or regulations.  
Privacy Policy Changes
Mozilla may change the Firefox Privacy Policy from time to time.  Any and all 
changes will be reflected on this page.  When Mozilla changes this policy in a 
material way, a notice will be posted on www.mozilla.com.  Substantive changes 
may also be announced through the standard mechanisms by which Mozilla 
communicates with its users and community, including Mozilla's "announce" 
mailing list and newsgroup.  It is your responsibility to ensure that you 
understand the terms of this Privacy Policy.  You should periodically check 
this page for any changes to the current policy.
For More Information
You may request access, correction, or deletion of Personal Information or 
Potentially Personal Information, as permitted by law.  We will seek to comply 
with such requests, provided that we have sufficient information to identify 
the Personal Information or Potentially Personal Information related to you.   
Any such requests or other questions or concerns regarding this Policy and 
Mozilla's data protection practices should be addressed to:Mozilla Corporation

Appendix for Pre-Firefox 3.0
Crash-Reporting Feature for Firefox 1.0-2.x.  
For these earlier versions of Firefox, “Talkback” is Firefox’s crash reporting 
feature.  Talkback also gives you the option to provide your Personal 
Information and Potentially Personal Information (including your name, email 
address, and the url you were visiting) and Potentially Personal Information 
(including your computer’s name, IP address, and the processes you were running 
at the time of the crash).  You can selectively disable the sending of this 
information.  Additionally, you have the option to include the URL of the site 
you were visiting when Firefox crashed, a comment, and your email address in 
the report.  Mozilla only makes Non-Personal Information and Potentially 
Personal Information in the public reports available online at 
http://http://talkback-public.mozilla.org/.
Security for Firefox 2.0 to 2.x.
Protection Against Suspected Forgery Sites. The Firefox web forgery protection 
feature displays a warning if the website you are visiting is suspected of 
impersonating a legitimate website.  Firefox lets you select various levels of 
protection, and different information is transmitted by Firefox depending on 
the level you choose.  
By default, Firefox checks the web pages that you visit against a list of 
suspected web forgeries (a “blacklist”) that is downloaded to your hard drive 
at regularly scheduled intervals (e.g., approximately twice per hour), the rate 
of frequency may change from time to time.  If there is a match, Firefox 
displays a “Suspected Web Forgery” alert.  Each time Firefox checks in with the 
third party provider to download a new blacklist, Non-Personal Information and 
Potentially Personal Information, such as the information that the browser 
sends every time you visit a website as well as the version number of the 
blacklist on your system, is sent to the third party provider.  In order to 
safeguard your privacy, Firefox will not transmit the URL of web pages that you 
visit in this default mode to anyone other than Mozilla and its service 
providers. 
You may completely turn off the web forgery protection feature in Firefox’s 
preferences.  If you do this, none of the information discussed here will be 
downloaded to your hard drive or sent to any third party service provider.
Each time Firefox checks in with the third party provider to download a new

third party provider.  In order to safeguard your privacy, Firefox will not 
transmit the complete URL of web pages that you visit to anyone other than 
Mozilla and its service providers.  While it is possible that a third party 
service provider may determine the actual URL from the hashed URL sent, 
Mozilla’s policy is to require its third party service providers to enter into 
a written agreement with Mozilla not to use any data or other information about 
or from users of Firefox for purposes other than to provide and maintain their 
service.  In addition, Mozilla’s policy is to prohibit its third party service 
providers from correlating any Firefox user data with any other data collected 
through other products, services or web properties of that provider. These 
third party service providers may inform you about additional notices regarding 
their applicable privacy policies.
