Mozilla may extend Firefox on Windows 7 and 8.1 support. The company has scheduled its end of support for January 2023, but now considering shifting the EOS date.
Most popular browsers terminate support for Windows 7 as it is no longer supported. Chrome will not get updates on this legacy OS starting in February 2023. So Firefox may become the browser with the longest Windows 7 support.
Windows 7 is not yet completely abandoned by users. While it not officially supported by Microsoft, it holds the third place among popular operating systems.
Keeping Firefox available for Windows 7 will allow Mozilla to get more users. On the other hand, supporting it will require testing the browser for it, and have the appropriate test automation infrastructure up and running.
Anyway, the extended support time frame for Windows 7 won't be long. The bugzilla post suggests that Firefox may remain available just until August 2023, with the appropriate ESR version. Mozilla is yet to decide what to do.
