Sticking with Windows 7? Mozilla says it will continue to support Firefox for more than a year
There are still a lot of people running Windows 10 rather than upgrading to Windows 11. This is perhaps not astonishing, but there are still a surprising number of users with even older versions of Windows.
With Microsoft no longer supporting Windows 7 or Windows 8.x, sticking with these editions of the operating system is clearly an inadvisable security risk. But for anyone who has no choice, or who simply refuses to move on, Mozilla will continue to offer security updates for Firefox under these versions of Windows until well into 2024, so at least your browser will be safe.
