Learn how Firefox will continue to support Windows 10 even after Microsoft ends updates and what steps Mozilla recommends.

Windows 10 will reach EOS (end of support) on October 14, 2025. After that date, Microsoft will no longer release free security updates or bug fixes for the operating system. {warning}'''Important:''' You can get a free one-year Windows 10 security update extension if you back up system settings to OneDrive via Windows Backup. You must have a Microsoft account. For more details, see Microsoft’s [https://www.microsoft.com/windows/end-of-support End of Support page for Windows 10].{/warning} If you're a Firefox user on Windows 10, you may wonder what this means for your browser experience. You shouldn’t worry: '''Firefox will continue to support Windows 10 for the foreseeable future'''. __TOC__ =Will Firefox continue to support Windows 10?= '''Yes.''' Firefox on the '''Release channel''' will continue to support Windows 10 users, even after Microsoft ends updates for this operating system. Mozilla has not announced any end-of-support date for Windows 10, but if one will be set, it’s '''still several years away'''. If you’re using Firefox Release, no action is needed. The Firefox browser will keep receiving updates, security patches and performance improvements, and you should be able to run it without any crashes or issues. =Do I need to use Firefox ESR to stay supported?= '''No.''' While Windows 7 and 8 users can only use Firefox ESR 115, '''Windows 10 users do not need to switch to ESR'''. However, '''Firefox Extended Support Release (ESR) version 140 does support Windows 10''' and next year's '''ESR 152''' will also include support for Windows 10. Firefox ESR receives monthly security updates, but it's enhanced with new features only once per year. As a result, you will have a stable browsing experience without any unexpected new features disrupting it. So the choice is yours: you’re welcome to use Firefox ESR on Windows 10, and you’ll have support for it in the years to come. =Mozilla recommends you should prepare for the future= While Firefox will be supported on Windows 10 long after the operating system’s end of support, Mozilla encourages users to take additional steps to stay secure: *'''Upgrade to Windows 11''' if your computer is eligible. *If you want to stay on Windows 10, consider '''Microsoft’s Extended Security Updates (ESU)''' to receive critical patches.
