[Mozilla Enterprise] Lock install xpi file Firefox 45.9.0 ESR

2017-08-25 Thread Tony Chambon

Hello, 

I want to block add-on (xpi) for all users , i use mozilla.cfg 

it's good for: 
xpinstall.enabled > false 

it does not work its rules: 
extensions.hideInstallButton > true 
extensions.autoDisableScopes > 0 
extensions.enabledScopes > 15 

I want to block any manual installation attempts after saving an extension 
(install an xpi file) 

regards

Hi Chris,

Does that settings change correspond with any file or registry edit?

I don't think Firefox supports Windows Group Policy, but you can change Flash 
from "Ask to Activate" to "Always Activate" by setting the about:config pref 
"plugin.state.flash" to "2". (Pref value 1, the default, is "Ask to Activate" 
and 0 is "Never Activate".)

Hi Chris,

Thank you for this feedback.  We are actually releasing an edition of i-Ready 
on Sunday that will have this detection in place for all browsers.  Users will 
be able to “self-help” themselves when they encounter Flash blocked by default.

In all of my research, I have yet to find a domain level policy that can be 
added to set Firefox to always “click to activate” either all together, or for 
specific sites.  If you know of a way, please let us know.

Thank you,

Subject: Re: Flash Allow List

Hi John, Firefox does not have a whitelist of sites that can load Flash without 
user action ("click to activate"). When users load your site, they will either 
see the "Activate Adobe Flash" UI in the web page (if the Flash content's 
dimensions are large enough) or a tiny plugin icon in the address bar (for 
Flash "pixels" that are too small for the UI).

I recommend that you add a check for Flash being installed and activated. If 
Flash is installed but not activated automatically, your page can show 
instructions guiding users to click the "Activate Adobe Flash" and "Allow and 
Remember" buttons. A dedicated workflow like this to test for click-to-activate 
is probably more user friendly and reliable than just loading your regular 
Flash content and hoping users see and click the "Activate Adobe Flash" when 
your Flash content doesn't show up.

In Firefox, Flash in click-to-activate mode will still be detectable by 
JavaScript in the navigator.plugins[] array (i.e. navigator.plugins["Shockwave 
Flash"]). Your JavaScript can detect that Flash is installed but not activated 
by embedding a Flash  that reports whether it is running or not by 
setting some JavaScript variable using Flash's ExternalInterface. I don't know 
if someone has already written a JavaScript+Flash library that already handles 
this click-to-activate, but I would love to know. In Chrome, however, Flash in 
click-to-activate mode will NOT be detectable in the navigator.plugins[] array, 
so JavaScript can't differentiate between Flash not be installed from 
installed-but-not-activated for this site.

Sorry. I think Firefox stores its about:config prefs in a SQLite 
database file, so you would not be able to safely modify the prefs by 
editing the file or the registry.

Have you tried executing any other GTK3 application in your setup? Let's see 
if the problems are the same there. You could also try to rebuild Firefox 
52esr with GTK2 instead of GTK3.


The Red Hat 6 / CentOS 6 / Scientific Linux 6 rpm packages of firefox 52.3.0esr
are build against GTK2 (gtk2 >= 2.24). You may be able to use one of these 
packages, or the binaries inside, rather than compiling your own version 
to test.


I'm running firefox-52.3.0-3.el6_9.x86_64 on a Scientific Linux 6.9 
machine, displaying on an android tablet running either bNVC Free or

RemoteRipple.
I use twm window manager but not Classic Theme Restorer
or Classic Toolbar Buttons.

Alt-F brings up the File menu when I am in normal, multi-tab 
mode, but not when I switch to "full-screen, no menu-bar" mode with F11.

In the normal mode I can also use the mouse to navigate the
file/edit/view menus that Paul highlighted in
   http://iment.com/paste-bin/Firefox-CTR-CTB-VNC.jpg

However the same is true for me on the console - I see
no difference with and without Xvnc.
