Mozilla Firefox browser 2025
During a recent AMA session on Reddit, Mozilla engineers revealed that the company plans to extend Firefox support on old, now-unsupported operating systems, such as Windows 7, 8, 8.1, and macOS 10.12-10.14. Mozilla did not reveal any specific timeframes, but now, it appears we have more information on that.
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.
Initially, Mozilla planned to ditch Windows 7-8.1 support in September 2024 but changed its plans. Now, Mozilla offers two ESR releases: 115 for unsupported operating systems and 128 for Windows 10 and newer. Removing Windows 7 support from Firefox 116 and onward allowed Mozilla to clean up the code base and removed the burden of maintaining newer libraries that no longer support pre-Windows 10 releases. At the same time, Mozilla says there are enough Firefox users on Windows 7, which justifies the extended support:
Firefox is the most popular and fastest browser for testing and
previewing our apps while development. It is completely free and
provides lots of dev tools for our app performance testing. It consumes
less resource as compared to other browsers. It supports web console for
testing JS code. Its also cross platform compatible for better
experience on all our devices.
