Installed it on 11/05/2015. No issues so far with my OS. v42.0.1 on Android is another story though. Crashes and stalls a lot.

New Firefox 43.0 released. See first post for more details.

New Firefox 43.0.1 released. See first post for more details.

Well, I must congratulate Mozilla Team, this version is way better than previous iterations, now HTML5 is more stable, yah, my VGA is still blacklisted, but you just tweak a pair of config values, and HD@60fps videos play smoothly. In general, the browser feels less sluggish.

Well done Mozilla!

New Firefox 43.0.2 released. See first post for more details.

Got it!

Never had a problem but it's installed.

Thanks

New versions and updates every day now? I just installed FF ESR 38.5.2 and now a new version
43.0.2. I know that is a complete new version install but still, why go through this almost daily lately?

Well that screwed it up pretty well so off to reinstall my previous version.

Now back to where I was with all addons I put in enabled just as I like.
Security be damned but I ain't achang'n again.

jamis · Dec 24, 2015

FF v43.0.2 installed on 12/23/15. No issues with anything, including plugins and addons. Even seems to load a bit quicker.

Baddog22556 · Dec 24, 2015

If everyone's system was configured the same then the same success or failure rate would be the same.
But still it is amazing how some software can accommodate so many varieties of hardware and
configurations of addons and such. I just don't have the patience to fix something that ain't broke.

New Firefox 43.0.3 released. See first post for more details.

jamis · Jan 1, 2016

Interesting. Both FF installs on my PC and Android tablet don't recognize that v 43.0.3 is available. PC is at v 43.0.2 and the tablet is at v 43.0. Both systems are set to auto update for FF. FF on the PC says it's up to date when checked. Not an issue, but this is the first time it's not flagged the update. I usually wait a day or two anyway as the updates usually fail the first day due to server issues.

Layback Bear · Jan 1, 2016

I have installed 43.0.3 on two system about 2 days ago without any problems.
I did it manually like I always do.

Release channel shipments of new builds are always throttled (released gradually to a portion of users at one time).
But 43.0.3 shipped on Dec 28.
I would expect you ought to have received it by now, assuming your auto-updates are properly configured and the download is not being blocked (e.g. by a security application).

You can always download the full installers (not the stubs) here (this is the US site):

Tonight, the FF install on my system did the 43.0.3 update. No issues with any plugins or addons. Just sort of strange that it took this long this time.

New Firefox 43.0.4 released. See first post for more details.

Just checked FF on my system and it's at 43.0.4 without my intervention! I just did the update to 43.0.3 yesterday. I checked the update option and it was set to automatic update. Previously, it had been set to notify. I reset it back to notify. Very strange.

jamis · Jan 7, 2016

I'm finding v43.0.4 is horrificly slow to load. I'm now getting pop up box at the bottom of the screen asking if FF is slow to load and suggesting doing a "refresh" of FF to fix it. After reading the linked page, I'm not sure what's amiss here and not sure I want to do the refresh. Perhaps I'll live with it for a while until I have time to mess with the plugins and addons. Maybe there'll be a v43.0.5 out soon that may correct things (or make them worse).

Layback Bear · Jan 7, 2016

If you are having problem with version v43.0.4 I would suggest it's possible the plug in's causing the problem.

I'm using v43.0.4 and not having any problems.
I always do a update manually with only my security running and Firefox of course, nothing else. I reboot Firefox and then reboot the system.
Then I check for updates for add-on's.

jamis · Jan 8, 2016

Well, I booted up this morning with the intention of working on the slow load issue, but v43.0.4 is loading within two seconds. No changes to plugins, addons, or anything. Something else was at play and I don't see anything that could have caused it. Maybe the multiple runs of CCleaner that we do did something. As Emily Latella would say "Nevermind!".
