It meant we couldn’t do other things, since we were busy with XP,” Mozilla says.

“It required effort, and it required devoting resources to supporting XP well after Microsoft stopped doing so.

With Chrome no longer supporting the platform since version 49 and Internet Explorer 8, the browser most used as standard on the platform, getting no security updates for more than two years, Windows XP users are left with no major browser than could keep them safe from exploits while navigating the Internet.Īlthough still widely used in organizations, Windows XP is currently a nearly-17-year-old operating system that hasn’t received security patches for over four years (although Microsoft did release emergency fixes last year, to address Shadow Brokers-related bugs exploited in the global WannaCry outbreak ). While Firefox ESR 52 continues to be available for download, it no longer receives security patches, meaning that any vulnerability found in the browser will remain unpatched. If this trend continued without much change after we switched XP users to ESR, XP Firefox users would presently amount to about 2% of release users,” Mozilla says. By the end of February 2017, XP users made up 8% of release Firefox.

“At the end of February 2016, XP users made up 12% of release Firefox. With these releases, Mozilla cut support for Firefox ESR 52, which was the last version of Firefox with Windows XP support. On Wednesday, Mozilla announced the release of Firefox 62 and also revealed that it updated Firefox ESR ( Extended Support Release ) to version 60.2. Last year, the organization said support for Windows XP was expected to be dropped by June 2018, but the browser developer took a few more months to make that happen. More than four years after Microsoft stopped supporting the platform, Mozilla is making a similar move.

Effective this week, Windows XP is no longer supported by Firefox.
