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). In short, there will be no more updates, including most importantly of all, no more security updates, leaving XP users with only one place to go – Opera – which ceased development with version 36 in 2016 but said it would continue to provide security fixes. (Anyone running Windows Vista should assume that the same browser support timelines outlined above apply to them too.)
