Good news, the Firefox release calendar says there comes a mega extension for 115 ESR until as late as Jan 2027! https://whattrainisitnow.com/calendar/

He says can't test on Operating Systems other than W7. I have no any problems found running on W8.1, it's works perfectly i think. By the way W8.1 is technically more as W10/11 than 7, so it is strange if it are workjing on 7 and NOT on 8.1 But actually, I rarely work with Windows anymore and usually use Ubuntu. It is just a kind of curiosity of mine to keep up with this browser support on W8.1. I got stuck on 8.1 because W10/11 never interested me.

Milestone 153 (ESR).

@Jody Thornton ???? Don't understand you. Only see Search Settings, but don't know any idea what the problem with that is.

Milestone Chrome 150:

good news: Mozilla has reversed Firefox 115 ESR support for Win 7+, now 115 ESR supported until August 2026. see: https://whattrainisitnow.com/calendar/

Chromium 147 https://github.com/e3kskoy7wqk/Chromium-for-windows-7-REWORK/releases

Milestone Firefox 150:

115 is only security fixes, no full updates. That could continue indefinitely, but I understand the choice they make to stop at some point. Now hope ESR 153 get to work. Stops definitive: https://www.security.nl/posting/925335/Firefox+stopt+vanaf+volgende+maand+ondersteuning+van+Windows+7+en+8

(Mozilla last updated 4 days ago), Firefox 115 ESR support is ended definitive on Feb 2026. https://support.mozilla.org/en-US/kb/firefox-users-windows-7-8-and-81-moving-extended-support

What you mean with penguins!!!!? Tux from the Linux operating system?

Is it known yet whether Firefox 115 ESR support will be extended in February 2026? It seems it will end permanently then, because I can't find currently any information about it being extended again. In a sense this is surprising, the W7 and 8.1 market share seems to be fairly stable, and Mozilla previously indicated that they considered the market share high enough to provide 115 ESR with security updates. On the other hand, I hope Firefox 153 ESR will work on W7 and 8.1, so we can continue with updates for at least another year. Pale Moon and CatsXP are still supported W7+ Supermium W XP+ without Widevine DRM (7+ with Widevine DRM) In total there are 5 good browser options now for W7+ Firefox 115 ESR Firefox 147 Fixed CatsXP Pale moon Firefox quamtum engine Supermium Do anyone known any another browsers supporting W7+?

https://github.com/e3kskoy7wqk/Firefox-for-windows-7/releases/tag/149.0a1 Run on W8.1

Do the Firefox 148 Nightly run on W8.1 and load websites?

Do the firefox 143 run on W8.1? (Hope 153 ESR in 2026 wil run)

On Webplayer and also on iPhone.

and 141?

CatsXP still working on W7 and 8.1 Can the Firefox 140 ESR run on W8.1?? Pale Moon also still suported W7/8.1

W7/8.1 Firefox ESR 115 support is extended to september 2025

Is this 8.0 or 8.1??? i see 8.0, NO start buton.

They are now hardcoded to require internal Windows files only present on W10+ And it is impossible to import/inject this files? Or rewrite them with another code to fake software? (as rewrite Windows libraries for Linux Wine)

can someone run newest Firefox on W7/8.1 now? I have found that that someone is successful to run Chromium 115 on Windows XP (and Vista i think) This version is also newer than the last official supported version on W7/8.1, Chromium 109. It is very strange to see the W10/11 UI on Windows XP. It was better that it run with the XP UI in my opinion. CatsXP kernel version 133 beta is out and running on W8.1.

Is there someone who suceed to run it on W7+ or W8.1+??

CatsXP Browser currently running on Chromium kernel 131 on W7+ NOW 132 BETA is out.
