Mozilla employee Mike Kaply revealed that the Firefox 115 ESR version released in July of this year will continue to support Windows 7 and 8.1 operating systems, and the browser will receive security updates and fixes until at least the third quarter of 2024. In addition, the Firefox development team has not yet chosen a specific date to stop supporting Firefox on outdated operating systems.
This means that “stuck” users of Win7 and 8.1 will continue to use a secure version of Firefox for at least another year. Its competitors Chrome and Microsoft Edge browsers have already terminated support for these two systems.
As early as the end of last year, Mozilla intended to extend its support for Windows 7 and 8.1 with Firefox. Data shows that about 15% of Firefox users are still running these two operating systems.
