The last one leaving windows 7

[disu1950]

Firefox 115 is now the last version supported on Windows 7.

Updates will be delivered through the ESR channel until the end of February 2026.
After that, users should upgrade their operating system to continue receiving Firefox security and feature updates.

The last one that supported Windows 7 has come to an end.
It was good while it lasted...
Stay well...

Numerous threads in this forum. Use R3dfox. Win 7 ain't dead yet.

Yeah the best I can tell. 115.33.0esr is the last update I'm expecting, and already have.

Regardless, I too am switching to R3dfox, though the portable version. To speed up the switchover, you can delete it's profile folder, and replace it with the one from Firefox 115esr, then what remains is a bit of GUI tweaking to make it look like the FF it's replacing... depending on how much you modified FF, though there's something something about a different rendering engine or whatever, the significance being that some GUI elements may still need tweaked if you're picky about it.

Those are in the Chrome folder, userChrome.css and userContent.css. IIRC there's also a setting in about:config that needs toggled for R3dfox to use these two files, though if you had set Firefox to do so previously, that setting may be inherited by R3dfox when you copy the profile folder to it.

The boxes I have running Win7 aren't changing OS any time soon. Since there's more than one, once I had the R3dfox portable tweaked, can just copy that folder over to any of them to use.

Personally, if you're running Win7 x32, the change I'd make would be to switch to Win7 x64 and put some more memory in that system. Win7 is still extremely usable with more than 4GB memory... depending on what software (version) you want/need to run on it.

Nope. Support extended 6 months.

Mozilla will provide security updates for Firefox 115 ESR until the end of August 2026. It was previously announced that support would end in February 2026, but in order to ensure our users can continue to browse the web, we will extend support another six months and re-evaluate. After that, if support is not extended, users should upgrade their operating system to continue receiving Firefox security and feature updates.
