Firefox 115 ESR Support Extended to March 2027

Mozilla has announced that it will be extending support for the ESR branches of Firefox 115 until March 2027. This extended support will be limited to users on Windows 7, 8.1, and macOS 10.12-10.14 platforms only. It is important to note that Firefox 115 is not guaranteed to work for other operating systems.

According to statistics provided by Mozilla as of August 10, 2026, 4.796% of Firefox users are still using Windows 7. This decision to extend support for older operating systems comes as a relief to many users who may not have upgraded to newer versions.
