Firefox 115 is the Last to Support Windows 7/8.x

Mozilla announced Firefox 115, the latest version of its flagship web browser, and the last that will support Windows 7 and 8.x. But no worries, hold-outs: Mozilla will continue delivering security fixes.

“In January 2023, Microsoft ended support for Windows 7 and Windows 8,” the release notes explain. “As a consequence, this is the last version of Firefox that users on those operating systems will receive. Users on Windows 7 and Windows 8 will automatically be migrated to the [Extended Support Release] (ESR) 115 version of Firefox so that they continue to receive important security updates.”

This is also the last Firefox version to support Apple macOS 10.12 (Sierra), 10.13 (High Sierra), and 10.14 (Mojave). As with the unsupported Windows versions, users on these macOS versions will be migrated to the Firefox ESR version 115 and will continue to receive important updates too.

Firefox 115 also includes some new features, like payment method import from Chromium-based browsers, hardware video encoding on Linux, the addition of close buttons on the Tab Manager drop-down, a streamlined UI for importing data from other browsers, and fallback support for the Cisco OpenH264 plugin when the PC doesn’t support H264 video decoding.

There are also two notable fixes on Windows: Magnifier now correctly follows the text cursor when the Firefox title bar is visible, and those with OS geolocation disabled can now approve geolocation on a case-by-case basis without causing system-wide network instability.

If you don’t already have Firefox, you can download it from the Firefox website.
