Important - Firefox is ending support for Windows XP and Vista
Firefox version 52 will be the last complete update for Windows XP and Windows Vista. Security updates will be released, but no new features.
Why is Firefox support ending for Windows XP and Vista users?
Firefox is one of the only browsers to offer any support for Windows XP and Vista. Microsoft itself ended support for Windows XP in 2014 and will end support for Windows Vista in 2017. Unsupported operating systems receive no security updates, have known exploits, and can be dangerous to use, which makes it difficult to maintain Firefox on those versions.
Will switching to a different browser keep me protected?
Unfortunately not. Most browsers (such as Google Chrome and Microsoft Internet Explorer) have already ended support for Windows XP and Windows Vista.
Can I still browse safely with Firefox?
In March 2017, if you were using Firefox with Windows XP or Windows Vista, you were automatically updated to the Extended Support Release (ESR) version of Firefox. If you visit the mozilla.org website to download Firefox, you will be offered Firefox 52 ESR.
Firefox 52 ESR security updates for XP and Vista users will continue until May 2018, although new features will not be offered. You will continue to receive important Firefox security updates but no other features or updates. You do not need to do anything else.
How can I get the newest features of Firefox?
If you want to keep your Firefox up to date, with all the latest features and updates, you'll need to upgrade your computer's operating system.
- Upgrade to a Windows version that Microsoft still supports, such as Windows 7, 8 or 10. Learn how here. Windows versions that are not supported by Microsoft are unreliable and unsafe to use, which also makes it difficult to maintain Firefox on those versions.
- (Advanced): Switch to a Linux-based operating system. Please see the support websites for the version of Linux that you're interested in.
