Windows 7 users can still access Firefox on the operating system for 6 more months, and Mozilla might extend it once again then.

Mozilla has announced that it will continue to support its Firefox browser on Windows 7, Windows 8, and Windows 8.1 until at least September 2025, as reported by Windows Report. Firefox 115 ESR will continue to support certain operating systems until September 2024.
