Firefox 3.6.29 and Firefox 12 (April 24, 2012) are the last versions of Firefox that work with the original version of Windows XP and Windows XP Service Pack 1. They won't be updated with security and stability fixes. In order to keep your computer and personal information safe, we recommend that you upgrade for free to Windows XP Service Pack 3 and install the latest Firefox. This article goes over your upgrade options.

Note: This article only applies to Windows.

Option 1: Upgrade for free to Windows XP Service Pack 3

For older versions of Windows XP, Service Pack 3 is a free upgrade from Microsoft. Installing this upgrade is the most secure option and will allow you to run the latest and greatest Firefox.

Option 2: Switch to Opera

If you can't upgrade Windows, you can switch to the latest version the Opera web browser.

Warning: Continuing to use the original version of Windows XP, Windows XP Service Pack 1 or Service Pack 2 is no longer supported by Microsoft and poses a significant security risk.

Option 3: Switch to Linux

If you can't upgrade Windows but want to keep your computer and information secure, you can replace Windows with Linux. Linux is a free and open source operating system that will allow you to run the latest Firefox.
