If you’re one of the millions of holdouts still unwisely clinging to Windows XP, Mozilla’s Firefox browser just waved you goodbye.
It’s a connection to XP that started with Firefox’s public launch in 2004, and ended with version 52 in March 2017, after which support for the obsolete OS continued under the Extended Support Release Channel (ESR) which staggered on until version 59.1.0.
Mozilla has used this week’s launch of Firefox 62 as the moment to cast XP adrift for good, justified because the company believes the OS makes up only 2% of Firefox’s user base, down from 8% in 2017.
Firefox has lasted longer than Chrome, which ended its support with version 50 in 2016, and Microsoft itself which stopped supporting XP’s native browser, Internet Explorer 8, two years earlier (although security updates were said to be possible via server versions).
Mozilla is pleased that it soldiered on alone:
That’s millions of users we kept safe on the internet despite running a nearly-17-year-old operating system whose last patch was over 4 years ago. And now we’re wishing these users the very best of luck.… and that they please oh please upgrade so we can go on protecting them into the future.
(Anyone running Windows Vista should assume that the same browser support timelines outlined above apply to them too.)
Firefox finally casts Windows XP users adrift
