Mozilla is planning to cease support for Windows XP and Vista after the release of Firefox 53, scheduled for March 2017. This implies that Firefox 52, the upcoming release, will be the last version to support the outdated Windows XP and Vista. To continue browsing, users will have to accept using outdated features, without receiving security patches, or switch to other browsers that still provide support.
The launch of Firefox 53 will mark the end of support for Windows XP and Windows Vista.
However, it's currently unclear if Mozilla plans to block and cease support for older mobile versions of the Firefox browser.
A noteworthy point is that from April 2014 until now, Firefox users on Windows XP have not received any new security updates. Firefox's competitor, Google Chrome, also stopped supporting XP and Vista in April 2016. Despite being an outdated operating system, statistics indicate that Windows XP still appears on 9% of computers worldwide, even though Microsoft ended support for it in April 2014; Windows XP was released in 2001.
The launch of Firefox 53 will bring an end to all support for the Windows XP and Windows Vista operating systems.
Therefore, the optimal solution for this issue is for users to switch to alternative browsers like Chrome, Opera, or Coc Coc if desired. Alternatively, users can update to Windows 8 or upgrade to Windows 10 to receive the latest updates and features with ongoing support.
