Re: Intent to deprecate: MacOS 10.6-10.8 support

[Milan Sreckovic]

Perhaps we can exercise restraint on doing a wholesale removal of the <10.9 
code, as doing so could make uplifting to 48 and earlier more of a mess.  Maybe 
in a few weeks?

Yes, that's fine assuming it builds on try. Official builds will be
happening on 10.7 for a while yet.

So, given that users won't be able to install Firefox on unsupported
versions of MacOSX, and unsupported users won't be upgraded, can we proceed
to remove all the nsCocoaFeatures::On[Mountain]LionOrLater() calls in
Firefox 49 and just assume everywhere that MacOSX specific Gecko code is
running on 10.9 or later?

Existing users should not be upgraded.

The Mozilla website will use UA versions to redirect users on these
versions to a SUMO page.

If a user does end up downloading and attempting to the DMG, the minimum
version is set in the app bundle and MacOS will show a warning saying that
this application requires a minimum MacOS version of 10.9.

Re: Intent to deprecate: MacOS 10.6-10.8 support

A google search on restricting the Mac version produced
LSMinimumSystemVersion and I found the following:

http://mxr.mozilla.org/mozilla-central/source/browser/app/macbuild/Contents/Info.plist.in#208

I don't have a Mac so I can't check what the behavior is.

Re: Intent to deprecate: MacOS 10.6-10.8 support

By design, dmg's don't do anything. There's no installer, just a
container with the executable ready to run. Nils reported in the other
thread that we just crash at launch time on 10.6, which is
unfortunate. I'd hoped Apple would show a 'not supported on this
version' dialog. We could including a warning background graphic, but
that's a poor experience for unaffected users.

Re: Intent to deprecate: MacOS 10.6-10.8 support

[Robert Strong]

Users won't get updated to an unsupported version and they will be notified
that their system is no longer supported. The notification includes an url
to a page for additional information.

I'm not familiar with the Mac installer but since it is just a dmg I don't
know if there is much that can be done. It would be a good thing if someone
that knows about dmg's could confirm or make our dmg do the right thing.

Re: Intent to deprecate: MacOS 10.6-10.8 support

[Benjamin Smedberg]

I thought this was already asked and answered, but just to be clear.

We are not going to make any changes to the ESR schedule or make Firefox 48
any kind of long-term release. The development costs of maintaining another
branch are high, and not something we're willing to pay.

Can we now make 48.0 a half-ESR? Firefox 49.0 starts to drop 10.6~10.8 as
well as machines which do not support SSE. Given we are still support them
with 45ESR, I think it makes sense to extend the support cycle of 48 to the
end of cycle of 45ESR.

Bug 1269790 only landed on mozilla-central. Shouldn't it then also be
backported to mozilla-aurora so it will hit the 48.0 release?

I didn't know we intended to drop support in 48. I just assumed 49 from
reading the blog post and knowing that things were just landing in nightly.
At this point, though, I don't want to do uplifts and would prefer that
this ride the 49 train.

Re: Intent to deprecate: MacOS 10.6-10.8 support

Yes. The intention was 48.0. Given that that doesn't actually buy us
anything at this point, dropping support in 49.0 is fine.

This was discussed in 
https://bugzilla.mozilla.org/show_bug.cgi?id=1269811#c7. It's 
technically possible to do, but it didn't seem worthwhile on Nightly and 
Aurora.


I intend to make sure that Beta/Release/ESR is configured in such a way 
that users get the most up to date release possible. Eg: serve 10.6-10.8 
users the latest 48.0 point release, then give them a deprecation notice.

I agree. At least users should get updated to the latest version in their

Right now I started a Nightly 40 on 10.6.8 and it simply refused to do any

Re: Intent to deprecate: MacOS 10.6-10.8 support

Right now the code to disable 10.6 has landed only on nightly/49, and other
bits are still blocked (see bug 1270217) because our MacOS builders (not
the testers) are still running MacOS 10.7. As of this point, I expect that
Firefox 48 will still run on 10.6-10.8 and the first release to drop
support will be Fx49.

If anyone wants to follow along, the tracking bug for the various pieces of
client, updater, website, and SUMO changes are being tracked in bug 1255589.

Why do Firefox DevEdition users on Mac OS X 10.6 then still get updates to 
DevEd 48?

I just tested it on a 10.6 machine and updates have stopped for Nightly. Which 
is good, because the Nightly 49 build which I manually downloaded crashes and 
brings up the Mac OS X crash reporter.
But the DevEdition installed on the same system updated itself to 48. And 48 
started and appeared to be still working.

I couldn't agree more. If you do not believe people can mix up and/or confuse 
what seems like an obvious statement or instructions, have a room full of 
college students read and explain it back to you.

The post states "Mozilla will end support for Firefox on OS X 10.6, 10.7,
and 10.8 in August, 2016." This means that we will end support with the
Firefox 48 release. i.e. Firefox 48 will not support OS X 10.6-10.8.

This post reads to me that we start dropping 10.6~10.8 since Firefox 49, so
Firefox 48 should be the last one with that support. Am I missing something
here?

48 is the first version that will *not* have 10.6-10.8 support.

It's Firefox 48, three versions after ESR 45, which is roughly halfway
before the next ESR.

Could we probably make Firefox 48 a half-ESR, whose support term is
extended to the end of ESR 45, so that people don't need to downgrade to
ESR 45 to get security updates for the rest of the time, and enterprises
don't need to deploy this version if they do not have many affected
machines.

Making the upcoming final 10.6–10.8 release (Firefox 47?) an ESR is an 
interesting idea. It's a unfortunate that ESR 45 was just released. 
Enterprises may already be deploying ESR 45 and not want to test and

(Note: Please see "OSX Support Cycle" below.) 

These are important decisions. However, expecting all end-users to be able to 
handle a manual migration to ESR, or understand what is happening or why seems 
like a bad idea. I believe downgrading should NOT be considered as an option, 
except for tech savvy users. 

There are three options that OSX 10.6-10.8 users have with Firefox:
1. Upgrade their OS (not possible for some)
2. Install ESR (temporary fix that could create problems if they can do #1 
later)
3. Continue using the unsupported Firefox (and hope they are not hit by a 
security vulnerability)
4. Stop using Firefox

Make sure that adequate startup pages are created to communicate these changes 
in as concise a manner as possible. Provide links for further detail. 
Subsequent startups should load follow-up pages with reminders, perhaps reduced 
to a notice bar (like what Google Chrome did recently).


SIDEBAR: "OSX Support Cycle"  ...

While we are on this subject, what is the plan for Firefox support of 10.9 
later this year when Apple pushes out its latest OSX? How about a year from now 
when 10.10 support ends? Where does the annual Firefox/OSX support depreciation 
end? 

Apple has shifted to warp speed with their rapid release cycle. Every version 
of Windows has a minimum 10 year support lifecycle (security patches, etc.) OSX 
now has 3. 

If Mozilla and other developers simply follow Apple's "not supported" timeline, 
there will be a growing number of end users who will be left out. Where do you 
think they will go? If they migrate to Windows there is a much greater chance 
they will stick with Edge or whatever is there and leave Firefox behind.

I have been a long-time Firefox advocate. I hope to continue this but am 
uncertain where the Firefox support path is going...

We *don't* follow Apple's timeline though.  Snow Leopard was dropped by
Apple back in 2013.  Mozilla's decisions are driven by considering, among
other factors, how many users remain on that platform and the engineering
difficulty of continuing to support it.

(Note: Please see "OSX Support Cycle" below.)

These are important decisions. However, expecting all end-users to be able to 
handle a manual migration to ESR, or understand what is happening or why is 
somewhat flawed. I believe downgrading should NOT be considered as an option, 
except for tech savvy users.

The best option, from my perspective (supporting a wide array of users, OS 
versions, hardware), is to make the final 10.6-10.8 version be (or become) the 
next ESR with a startup page providing them with the choice and action 
buttons/links. Subsequent startups would load follow-up startup pages with the 
appropriate reminders.

The pages should explain very simply and succinctly that no new features will 
be coming and only security updates/patches will be made until "X" date when 
support ends (but the browser will still be usable). The first page should be 
VERY overt and obnoxious. The 2nd, 3rd, etc. can be more like what Google 
Chrome did recently (ie. notice bar at top of the content area).

Indeed.

As noted up-thread, the availability of the Widevine CDM (as of
Firefox 47) provides a migration path for Silverlight-using sites.
Supporting Firefox via Widevine should be particularly easy for sites
that have already adopted Widevine in order to support Chrome after
Chrome dropped Silverlight and have moved to unprefixed promise-based
EME so as to keep working in Chrome 50. As a success anecdote,
Bitmovin's player did the Right Thing by feature sniffing instead of
browser sniffing, so their player Just Works without Firefox-specific
changes. See http://www.dash-player.com/demo/drm-test-area/ for demo.
(Services that use Widevine with WebM [Microsoft Azure is a known
example] don't work yet. EME support for WebM support is
https://bugzilla.mozilla.org/show_bug.cgi?id=webm-eme)

I encourage people who have @mozilla.com Google Docs access to add the
Silverlight-using movie streaming services that they are aware of in
their country to
https://docs.google.com/spreadsheets/d/156hS5R42R8evZlMKIwnliNWidJpqH2HDINvrjyqMVFE/edit
so that migration off Silverlight can be tracked.

There appear to be a couple of non-intranet non-video
Silverlight-using sites in Japan. Obviously, Widevine doesn't address
Java-esque use of Silverlight, but it's relatively rare outside
intranets generally.

I don't think so. I also don't know that we're going to recommend that
users migrate to ESR (need to verify that there are no incompatible profile
changes) although that is certainly an option.

Is it feasible to make 48 an ESR as well so that we don't need to ask users
to downgrade it to ESR 45?

We discussed this earlier and decided that we were not going to
automatically move users from Firefox to ESR. For one thing, the user has
not opted to be on this channel. A channel change also involves both
engineering and test work. It does seem prudent to test the scenario to
know whether users can move from 47 to ESR 45.2.0 without issue.

IIRC the problem isn't that people are running 32-bit Firefox it is that
certain plugins only have 32-bit versions. So e.g. a 64-bit OS X 10.10 is
still running a 32-bit plugin process for certain plugins.

I think the data we need is how many users are running 32-bit NPAPI
processes on OS X > 10.8 (only the 10.9+ population is relevant because
we've dropped 10.6-10.8). Then we can have a conversation about dropping
32-bit NPAPI on OS X before 53.

Did we introduce changes to profile data between 45 and 48? Because
that usually breaks downgrade paths.

That doesn't mean we can't remove 32-bit NPAPI support on OS X sooner 
than 53. Most enterprises are probably using Windows and not 32-bit OS X.


bsmedberg's OS version dashboard (for Firefox 42 in November 2015) says 
only 1.4% of OS X users were running 32-bit Firefox. btw, 16.5% of OS X 
users were still running 10.6.

Is there a bug tracking NPAPI removal?


No, so I just filed bug 1269807 (Bugzilla alias "remove-npapi"). Feel

App update has the ability to show the user a message that the system is no
longer supported based on the update.xml served by release engineering.

A number of actions have already been performed to formalize the
deprecation of these OS X versions:

* Treeherder no longer shows tests running on <10.9
* The minimum OS X target version has been bumped to 10.7 meaning that
builds will shortly not work on 10.6 (bug 1269790) (see bug for why 10.7
and not 10.9)
* The update server has been reconfigured to not serve Nightly updates to
10.6-10.8 (bug 1269811)

Then we should plan to drop Universal builds in the same release,
because without supporting 10.6 or 32-bit NPAPI plugins, the 32-bit half

I don't know the status of 32-bit Silverlight on OS X, but we're shipping
Widevine support in Firefox 47 (for Windows 7+ and OS X 10.6+). Streaming
services will have an easy migration path from Silverlight to their
existing Widevine player code.

Fair enough.

So what's the last Firefox release to support NPAPI plugins? 50? 51?


We're tentatively planning to remove NPAPI support (for plugins other 
than Flash) in 53 because 52 is the next ESR. We'd like ESR 52 to 
support NPAPI as a transition option for enterprise users that rely on Java.

Yes, please. We can't take advantage of any of the engineering
benefits until we stop gating builds on tests passing on 10.6.

Mac has EME-based support for DMCA-protected video starting in Firefox
47[1], so there's an alternative to Silverlight for those sites. There
are other uses of course, but we have previously announced an end to
native NPAPI plugins at the end of 2016[2] so I think that's the
timeframe for dropping 32-bit mac support. If we want to make progress
in the meantime we should start doing separate 64-bit only builds, and
use the update process to transition users on Mac > 10.6 who don't
have 32-bit plugins to the new 64-bit builds.

So this presumably means we can turn off automation running on 10.6-10.8 on
mozilla-central? I believe that will drastically increase our OS X
automation capacity...

So where does that leave us on Universal OS X builds? IIRC our blocker is
the need to support 32-bit Silverlight in the plugin container so various
streaming services using it don't break. Where are we on that front?

The blog post just says "August 2016". Firefox 48 is scheduled for

Should we have made this decision and announced it before the 46 release? I
would have liked that. The timing certainly seems better. Should we
continue supporting OSX 10.6-10.8 in Firefox until mid 2017 because we
didn't make this decision a few months ago? I don't think so.

Re-re-ping.
Being able to use a more recent standard library would simplify a lot of
things on our end. For example updating 3rd party libraries such as

Re-ping on this thread.  It would be really useful to have a decision
one way or the other for figuring out exactly how a C++11 STL on OS X

Though in this case, the main competitor (Chrome) would also be dropping 
support. In fact they are even worse in that they are dropping all pre-Win7 
platforms while I proposed dropping support for only XP SP2.

Thanks for the explanation that makes perfect sense to me. By the way since
the questions is never if we drop support for a system but when do we do
it, would it make sense to track / measure of how much work went into
maintaining a particular system in the last x month (or will be in the next
month like in the e10s case)? I guess that data would help to make this
decision easier and with less debates (although there are ofc always
exceptional cases for fundamental releases like e10s).

The math is pretty striking: the problem is not so much about user 
acquisition but about retention and user engagement. We have no problem 
getting new Firefox users: we still have amazingly high brand 
recognition and get many downloads. In terms of retention, what kind of 
engineering effort do we need to do to keep users one, two, four, eight 
weeks after they've tried Firefox? In terms of ongoing engagement, the 
Firefox product strategy has us measuring and optimizing how many days 
(per week) Firefox users use Firefox.


Our basic product strategy is that by focusing our engineering efforts 
on engagement/retention of new users, we'll end up in a much better 
spot, both in terms of overall product quality and our position in the 
market, than if we focus on keeping small cohorts of existing users. 
That tradeoff of existing users for new-user engagement is driving our 
strategy with e10s, extensions, and other engineering priorities, and is 
the basis for this decision.

I have a laptop on 10.6. The hardware can theoretically support newer
OS X versions, and I've upgraded it, but newer OS X versions are
severely unstable on it, causing hangs and spontaneous OS reboots. So
I downgraded back to 10.6. I don't know if this is a common scenario
but given Apple's hardware uniformity I'm probably not the only one
who has experienced this. Just saying Rosetta isn't the only reason
people stay on 10.6 :)

here is the problem. Firefox has a different userbase than chrome.
In my perceprion it is people who are cautious, prefer stable interfaces, 
not attracted to blingbling and more focused on stability, privacy and 
security.

Much of the blingbling features which some developers die for are
a plain nuisance for a significant share of users.
It took 4 years to fix the autoplay bug at least partially?
 https://bugzilla.mozilla.org/show_bug.cgi?id=659285

This is what is driving away users.

Firefox won't win the blingbling race with Google and Co, maybe if it
focuses on its traditional userbase and their demands it would do 
better.

Re: Intent to deprecate: MacOS 10.6-10.8 support

[Justin Dolske]

I don't think it's entirely unfair -- both sets of numbers have their
place. OS X is an important platform, but it's also true that these older
OS X releases represent a tiny portion of our overall userbase.

For a few more data points...

Back in Firefox 16 when we dropped 10.5 -- another long-lived and popular
release -- those users represented 17% of our OS X users (or 0.78% of
overall userbase). Dropping 10.6 - 10.8 is about 1.5x the impact
(percentage wise), and so we should think carefully about that, but it's
not significantly out of character for what we've done before.
https://groups.google.com/d/msg/mozilla.dev.platform/aT7hy7YDdqA/j2O0bUnuYMEJ

When we dropped 10.4 (early in the Firefox 4.0 cycle, about a year before
release), it represented 25% of 3.5 users and 17% of 3.6 users. (I don't
see a overall userbase number in the thread.)
https://groups.google.com/d/msg/mozilla.dev.planning/fTpkdYa6uZM/9aPn58hvVa8J

And wy back when we dropped 10.3 (for FF3.0), it represented 16.5% of
OS X users, 0.69% of total user base.
http://groups.google.com/group/mozilla.dev.planning/msg/c19ecb46e27dbf91
http://groups.google.com/group/mozilla.dev.planning/msg/4bd908b72a5e0759

One thing all of these threads show is that there's a lot of noise and
handwringing and doomsayers when we broach the topic of dropping support
for an OS X release. :)

Is it? Are you confident that quality and stability of an up-to-date Firefox 
won't go downwards over time on those old platforms? It's not quite clear to me 
that it will perform better than ESR half a year or a year from now.

Re: Intent to deprecate: MacOS 10.6-10.8 support

My understanding is that the reason people stick to 10.6 is because
of Rosetta[1] which offers PowerPC compatibility.

https://en.wikipedia.org/wiki/Rosetta_(software)

Chrome is dropping support for these platforms so it seems like an
opportunity to pick up some of their discarded users. I'd rather
have a 1% gain in market share than a 1% loss. The question is
whether supporting 10.6 costs us more than 1% of our resources.

Some people may upgrade from 10.7 or 10.8 but last time I looked at
the graph I saw 10.6 was on very slow decay path probably inline
with hardware replacement.

10.6 has been more effort to support in the past (i.e. getting
decoders working) but I don't think it costs us more to maintain.

  It's unfair to mention those populations by
  percentage of the global
  Firefox population. What are those percentages relative to
  the number of
  OSX users? ISTR 10.6 represented something like 25% of the
  OSX users,
  which is a totally different story (but maybe I'm mixing
  things with
  Windows XP).

  
  

I heard much the same thing from the
  media team when I suggested getting rid of 10.6 support to
  make our C++ standard library situation easier.  CC'ing

Seems like a tough decision for such a short time...  There were some great
points on both sides so far, but I'm missing the math. To evaluate the
cost/benefit for a decision like this we should be able to estimate how
much engineering time does it take for us to gain 1.2% new users and how
much does it cost to keep the support. My personal estimation for the first
is pretty high :(

We also might miss the opportunity to gain new users on these systems, and
we risk a bad press as well, but I'm a little less concerned about these. I
just feel like there should be some other way to save engineering time that
costs less users but without the metrics I can only guess.

If the concern for user base is marketshare (as I've read and heard some
people claim, although maybe not Kyle), I'm not sure this argument holds
water for two reasons:

1. If we stop supporting an OS version today, all of the users on that
version will not immediately switch to an alternative.
2. In the case of older OSes, if there are no other browsers shipping
updates, there is really no alternative that is more attractive than the
browser that you've already picked.

This does not jive with the data bsmedberg provided in the OP, which shows
the 10.6 userbase being equal to that of 10.7 and 10.8 combined.

It's also worth considering what value we could unlock by dropping 10.6 and
keeping 10.7 and above. IIUC most of the pain on the engineering side (c++
standard library, TLS for rust, etc) is related to 10.6 specifically.
Things might be different in the releng world though.

Though actually, I think the reality is worse than that, because the curve
is probably non-linear. There's probably some relatively-discrete point
(which we can't easily predict) at which declaring Firefox an "unsupported
browser" becomes a sensible business decision for large, enterprise-y sites
that operate that way.

We should try very hard to stay above that threshold. I don't know how much
closer to it this proposal will bring us, but it's definitely more than
1.2%.

I don't think it's quite that simple.

I agree that it's important to recognize that users on older OSes have
lower long-term value to us, because we'll _eventually_ need to stop
supporting them, and there's no guarantee they'll reinstall Firefox if they
move to a new machine.

However, they _do_ have short-term value, in that their continued use of
Firefox makes the Web better for every other Firefox user. The number of
f***s web developers give about the experience of Firefox users is directly
proportional to the number of Firefox users visiting their sites. The lower
that number goes, the bigger our disadvantage, and the more engineering
heroics we'll need to do to compensate. By the time Opera/Presto went
under, rumor has it that almost all of their resources were going to
web-compat.

Its a regressive game that favors monopolists, but there you go. Ditching
1.2% of our users makes it materially more difficult to attract new ones.
So we should only do it if the benefits really outweigh the costs.

I'm happy to be more aggressive about ignoring 10.6-only regressions,
reducing testing, etc. If it keeps the costs manageable, I think it's
preferable to ship a possibly-sub-par experience to 10.6 users than to
jettison them entirely.

The reason for considering benefits of populations relative to their own OS
are because there are two kinds of things we get out of platform support.

One is greater impact resulting from a higher overall number of users.

The other is other strategic benefits we get out of platform support like
on Linux where user numbers are low, but gecko and firefox tootling and
testing developer contributions are relatively high.

For Mac there is a possible web dev connection that's of possible strategic
value with higher concentration of web devs on that platfor that help keep
sites working well for large numbers of others.

Dolske showed some numbers that reflects where in the decline in previous
Mac cycles that we removed support, but that could or could not be related
to our current problem of trying to find ways to stablize and stop the
decline of users.

Keeping these releases supported around just a bit longer than google gives
people incentive to come back and try firefox.  Just the thing we want to
happen.

If I look a a view of the numbers relative to all current Mac users it
looks like 10.8 has the highest value (15% of all current Mac Users) for
keeping around just a bit longer if their is any possible way to do that.
The others are in the noise.

Some one should check these numbers and see if they look right.

Version  % of all current Mac users as of back in Nov. which is the
latest data I can easily get my hands on to play with.

Mac10.8.00.1500

 Mac10.7.00.0004
 Mac10.7.40.0001
 Mac10.7.10.0001

I agree that looking at the total number of users is the correct way
to think about this.

There is some risk from a PR perspective though. I.e. headlines that
say "Firefox drops 25% of Mac users" would be unfortunate.

My impression is that non-e10s is certainly something that we'll want
to get rid of, but that we are not certain on what timeline it'll be
possible. Experience shows that big undertakings like that more often
take longer than expected, than go quicker than expected.

If we can support these users for another year, then that's certainly
a non-trivial benefit in and of itself. And it might also give users
time to migrate to more modern hardware.

Obviously, if don't think that we can support these users anyway, due
to already existing issues, then it could still be worth dropping
them. However "we're going to drop non e10s support in a year anyway"
doesn't seem like a reason to drop these users now.

Re: Intent to deprecate: MacOS 10.6-10.8 support

[Terrence Cole]

We've had this conversation several times in the last few years and I think
I've finally figured out why it has always felt subtly wrong.

Our share of users on older platforms is disproportionally high compared to
the market in general because of our decline in market share. People who
don't want to upgrade their OS generally don't want to "upgrade" their
browser to the shiny new "chrome" thing the kids are talking about either.
It is a symptom of a larger problem and it seems like we are continually
hiding from that problem instead of tackling it head-on.

We should be aggressively cutting support for niche markets and spending
that effort to increase our market share where it counts: where it's
growing rather than rapidly shrinking. Telling 1.2% of our (admittedly
small) market share to, effectively, GTFO, is pretty scary; however, I
think the alternative is to simply fail as a project as we chase our
users-by-default into more and more niche markets. If we can't use our
resources to re-capture 1.2% of the market among people who have modern
computers and no obligation to love us, then maybe we've already failed.

We need to drop support for OSX 10.8 and Windows Vista yesterday, not next
year. We need to cut our losses and ship E10S while we're still relevant.
We need to be the browser that works best on Android and Windows 10, not
the browser that happens to already be installed.

My 2 cents,
:terrence

If we change the macos target version, that's not possible. The
resulting binaries can't even be loaded by the dynamic linker on 10.6.

Why do you think this is unfair? This is about making the best use of 
our limited engineering/testing/QA resources, and so what really matters 
is the total impact, not just the impact relative to the mac population.

I’m only asking because of the opposing reply’s so far. I’m assuming it means 
we stop testing and building/releasing for these. Would it be a possible 
alternative to turn of the tests, but continue to build and release unsupported 
builds?

We intend to do the following things:

* add version checking to the builds so that they refuse to run on these 
versions of MacOS

* stop doing any software testing on these versions of MacOS
* stop automated testing on Mac 10.6

As soon as we stop testing, we are going to break things. We shouldn't 
be willing to call things "Firefox" that we aren't proud of, which 
includes real testing.

We did explicitly consider this option and ultimately rejected it. It 
would potentially buy us at least one more ESR cycle until next January. 
After that point we want e10s to be the only configuration. It comes at 
the cost of ignoring known issues already as well as a nontrivial amount 
of testing. Ultimately we don't believe this is the right tradeoff. It 
also prevents us making progress on other areas such non-universal builds.

1. their machine can die and they'll replace it with a new one that will
come with the latest MacOS, and restore their data from a Time Machine
backup.

2. they have some software that is important that require an update so
they will update - and since only updating to that latest OS is easy,
that's what they'll pick.

[Tyler Downer]

I'm not making any claims other than pointing out that the upgrade is
possible for some users, and its a workaround we can give in SUMO. I
have no other irons in this fire, just making sure we know the
workarounds (and how accessible they are) is an important piece of
this  decision.

As has been stated in this thread already, not all these users can
update, not all will, but they likely are some that just haven't
gotten around to it where upgrading is a good workaround.

This is actually a sensible option.
A not-quite top-notch but up-to-date Firefox is still better than old
versions of Firefox or other browsers.

That brings up a point, if a user is on 10.8, gets moved to ESR 45, and
later moves to 10.11, will they be stuck on ESR still?

We build Firefox targetting 10.6 with a development version of clang 3.8
(that is, a clang build from a svn revision during the 3.8 development
cycle). What *is* ancient is its libstdc++.

Re: Intent to deprecate: MacOS 10.6-10.8 support

[Syd Polk]

10.6 is the last version with Rosetta. Given how old the machines are that can 
run 10.6, and given how old 10.6 itself is, it is highly likely that 10.6 
customers still have PowerPC apps that they run and they cannot/will not 
upgrade.

Also, the perception of the Mac community in general is that 10.6 is the most 
stable release of OS X.

If you have old hardware (esp. if you have Power PC apps), there is very little 
reason to upgrade off of 10.6 until your hardware dies.

In the past, when these numbers were run, 10.6 was right on up there with the 
latest one or two OS X releases in Firefox usage, but 10.7 and 10.8 were almost 
gone.

I do, however, think that supporting 10.6 is a heavy, heavy burden, as its C++ 
compiler is truly ancient.

Just opinion, no recommendations here.

 It's unfair to mention those populations by percentage of the global
 Firefox population. What are those percentages relative to the number of
 OSX users? ISTR 10.6 represented something like 25% of the OSX users,
 which is a totally different story (but maybe I'm mixing things with

The other thing to note is many of those users can still update to 10.11,
and I imagine that over the next year that number will continue to go down.
This also provides a decent workaround that our support community can

Re: Intent to deprecate: MacOS 10.6-10.8 support

[Ryan VanderMeulen]

25% is pretty close for 10.6-10.8 combined. However, the current proposal
includes security patches for nearly a year still (putting them on the
ESR45 train), so construing this as abandoning those users seems like it's
going a bit far.
