Download Mozilla Firefox for Windows 7
Looking for Mozilla Firefox for Windows 7? If you download Firefox directly from the official website, you may not find a version that supports Windows 7 anymore.
The last major Firefox release that supports Windows 7 is Firefox 115 ESR (Extended Support Release). Mozilla’s ESR version was specifically designed to provide extended support and security updates for users who cannot immediately upgrade to a newer operating system.
For Windows 7 users, Firefox 115 ESR can be a useful alternative to Google Chrome. While newer versions of Google Chrome no longer support Windows 7, Firefox 115 ESR was released with continued compatibility for this older operating system.

Firefox 115 ESR is an important release for Windows 7 users because it is the final Firefox ESR version that supports the operating system.
Mozilla continued providing security updates for Firefox 115 ESR after regular Firefox releases moved on to newer versions. According to Mozilla’s support schedule, Firefox 115 ESR receives security updates until March 2027.
If you still use Windows 7 and need a modern web browser with continued security support, Firefox 115 ESR is one of the options worth considering.

Why Use Firefox on Windows 7?
One of the main reasons to use Firefox on Windows 7 is compatibility.
