Mozilla Firefox Release Schedule
The Firefox Release Schedule overview offers information about past, present and future releases of the Mozilla Firefox web browser.
With three different versions of the Firefox web browser available at any time (Stable, Beta, Nightly), plus special builds that pop up every now and then and ESR versions, it is quite difficult to keep up with the browser's rapid release schedule.
To make matters even more complicated, some versions like the nightly versions get updated fairly often. To bring order into chaos, release schedules usually only concentrate on version increases and not all the updates that get released.
Mozilla's official Release Schedule page lists only the next version upgrade for Firefox stable, beta, aurora and nightly, but does not go beyond that. (Update: That changed with the introduction of the Rapid Release Calendar)
While you can try to calculate the releases after the next by adding 42 days to a fixed release date, actual release dates may fluctuate especially for the beta and aurora version increases.
Update 2 (2019): Firefox will be released every four weeks from 2020 onward.
Update (2016): Mozilla announced the move to a variable Firefox release schedule recently.

The table currently covers all upcoming releases for the year, and even provides an outlook of the first releases of next year.
Mozilla Firefox Release Schedule
Our Firefox release schedule lists all Firefox versions, meaning Firefox Stable, Beta, Nightly, and ESR, the version they are updated to, and the date this is going to happen.

The release schedule for Firefox is regularly updated by us so that you will always know when future versions and editions of Firefox are released by Mozilla.
Since Mozilla moved from a 42 release cycle to a flexible scheme, it becomes even more important to keep an eye on these releases.
You have a few typos that are easy to fix.
In the release schedule:
“Firefox 96, Beta 97, Nightly 98, Firefox ESR 91.5 — 11.01.2021”
The date should be 2022
In the past releases:
“Firefox 24, Beta 25, Aurora 26, Firefox 24.0 ESR – 17.9.2013”
There are a number of lines with the accented character “” that are spurious
@ Martin,
There appears to be a way of preventing the move to update ESR from 52.6 to 59 in the CTR developer’s thread on Github. It would appear that if you decline the upgrade to 59, ESR will update to 52.7 thereafter to 52.8. Only after that will users be required to update to 59.2 which won’t support legacy add-ons anymore. Details are in the “Note” in the first post: https://github.com/Aris-t2/ClassicThemeRestorer/issues/299
The most irritating thing about firefox is the constant crashing on pages loaded with animated gifs.
try to make a new profile and see if it still happens
You either have a graphics or memory issue or your profile is messed up. Try a clean profile.
err…. *are NOT related to FF
Sounds like your system is infected or you’re incompetent but your issues are related to FF
I like Waterfox. Works great for me. Unload some of the add-ons if you are having issues (with any browser).
Could you perhaps make a comparison of Firefox vs Palemoon vs Waterfox?
Waterfox is just FF stable but 64bit,
Palemoon differs more ,it can change displaying your FF profile-especially if it was huge + very tweaked- then it is better to have different one , Waterfox64bit(there is only 64bit) works well with FF profile
IN both cases if U’re uninstall P/W be careful not to delete FF profile – that’s the only one caveats..Just have it backuped..
If till now you’re staying with stable FF realeses you can go for P/W , W esp. if you want 64bit , but if you like Nightly/ Aurora -stay with them – and well , who said that you should use
only one ?
for more: http://www.palemoon.org = 32bit and 64bit , also portable
http://waterfoxproject.org/
https://sourceforge.net/projects/waterfoxproj/
But G.Chroma replace with Chromium or Iron without hesitation
Other webkit options to look into : qupzilla , maxthon ,avant
Tried Waterfox. The same memory problems as with generic Firefox. Did not see any speed improvements.
First time I’ve heard of Waterfox. I’ll check it out. Thanks!
I tried Palemoon. I got tired of it always being a couple of versions behind generic FF. It is supposedly optimized for Windows with some features disabled. I honestly didn’t notice any difference. Ultimately I went back to FF just to avoid the hassles.
there’s also a palemoon version
http://www.palemoon.org/
and as well as Palemoon there is also Cometbird…used it for years.
