It's pretty incredible but Mozilla is still offering support for the Firefox browser on the ancient Windows XP and Windows Vista operating systems. This is slowly coming to an end though. Earlier this year, Mozilla moved Firefox users on these operating systems to the Firefox 52 Extended Support Release and now the developer reveals support will be dropped in June 2018;
Mozilla joins Google, who dropped support for XP and Vista back at version 50, released in April 2016, along with other older platforms such as OS X 10.6 Snow Leopard, OS X 10.7 Lion, and OS X 10.8.
Firefox users that still need a browser for their old and antiquated XP and Vista machines would have to use old Firefox and Chrome versions, but both Mozilla and Google recommended that users upgrade to Windows 8.1 or newer, for security reasons.
Windows XP reached the end of its life on April 8, 2014 and is no longer receiving security updates from Microsoft. Vista on the other hand received security updates until April 2017, but that version of Windows never really gained traction so it's easy to see why companies are dropping support much sooner.
Despite all security warnings, the latest statistics from NetMarketShare reveal 5.69 percent of users are still running Windows XP.
