Mozilla extends Firefox support on unsupported Windows versions to March 2025

Not too long ago, Mozilla announced it was going to extend its support for Windows 7, and was mulling over extending support for Windows 8.x as well, without providing any time frames or details. Well, we’ve got the details now.

According to the Firefox Release Calendar website, Firefox 115 ESR, the latest Firefox version with support for Windows 7, 8, and 8.1, will continue receiving updates until April 1, 2025. Firefox 115.21 ESR is expected on March 4, 2024, which means users with old Windows versions have at least seven more months of support from Firefox.

The same extension to March 2025 for Firefox 115 ESR also covers macOS 10.12-10.14. The reasoning behind the extension is simple: there’s still enough users on these older operating system version for Mozilla to dedicate resources to it, despite how difficult backporting security fixes to 115 ESR has become. Firefox is pretty much the only mainstream browser still supporting Windows 7 and 8, and that’s definitely commendable.
