Still using XP with Firefox? Your browser will stop running starting in September 2017 according to Mozilla.
In approximately March, 2017, Windows XP and Vista users will automatically be moved to the Firefox Extended Support Release (ESR).
Firefox is one of the few browsers that continues to support Windows
XP and Vista, and we expect to continue to provide security updates for
users until September 2017. Users do not need to take additional action
to receive those updates. In mid-2017, user numbers on Windows XP and
Vista will be reassessed and a final support end date will be announced.
In the meantime, we strongly encourage our users to upgrade
to a version of Windows that is supported by Microsoft. Unsupported
operating systems receive no security updates, have known exploits, and
are dangerous for you to use. For planning purposes, enterprises using
Firefox should consider September 2017 as the support end date for
Windows XP and Vista.
