Mozilla stopped supporting Firefox for Windows XP and Vista in June 2018

Today, Mozilla announced it would not offer any support for the Firefox browser on Windows XP and Vista in June 2018.

'As one of the browsers that still supports Windows XP and Vista, Firefox users on these operating systems still receive security updates until that date,' Mozilla said.

Earlier this year, Mozilla moved Firefox users on XP and Vista to Firefox 52 ESR (Extended Support Release). This was announced in December 2016, when Mozilla said it would give a final answer on whether to support XP and Vista again in September 2017.

Both major browsers have stopped supporting Windows XP and Vista

Mozilla followed Google, which ceased support on XP and Vista from Chrome 50 released in April 2016, along with other platforms such as Snow Leopard OS X 10.6, OS X 10.7 Lion and OS X 10.8. Anyone who needs to use an XP or Vista machine can still use an old browser, but it is recommended to upgrade to Windows 8.1 or later.
