Mozilla’s Firefox web browser continues to be supported on Windows 7 and older versions of Apple’s macOS operating systems, according to an update that Mozilla published on its website.
According to the update, Firefox ESR 115 support is extended until at least March 2026. Mozilla plans to evaluate the end of support again in March 2026 to determine whether it will extend support again.
Firefox is one of the few web browsers that continue to support Windows 7 and older macOS versions. Most browsers have ended support for the discontinued versions of Windows and macOS some time ago already.
Firefox ESR 115.33 will be released in February 2026. It could be the last version of that ESR branch, if Mozilla decides to end support then and there.
More than six percent of Firefox users use Windows 7. That is a large number, even with Firefox’s declining userbase.
Firefox 115 was released in 2023 initially. The Extended Support Release version of the browser is only supported with security and bug fix updates. New features are not introduced in the same ESR branch usually. The next major ESR release introduces the features that Mozilla released in stable Firefox in the meantime.
Since there is no upgrade for Firefox ESR 115 users, their version of the browser remains on the 2023 feature set. Means, features such as tab groups, vertical tabs and others are not available.
The consumer editions of Windows 7 are no longer supported by Microsoft. This means that the operating systems do not receive security updates anymore. Micro-patching service 0Patch continues to support the operating system, however.
They should release 115.40 along with 140.15 and no new release afterwards.
Is this Site no longer updated?
It is, was just on holiday the last 3 weeks.
The only problem with this now is that sites which use Cloudflare are blocking browsers which don’t conform to the latest standards. Changing the User Agent doesn’t work either since Cloudflare seems to be able detect when one of those is being used. So I think this latest Mozilla update will fall by the wayside pretty soon.
I think I’ll have to consider installing a Linux distro on my win 8.1 machine even though it’s an Optimus flavour and just use my other Windows 11 laptop for banking, filing my annual tax return and stuff like that. I definitely don’t want to use it for pleasurable purposes like reading Chipp.in and general web stuff because of the screen is way too small and because I positively detest Windows 11.
