Firefox for Windows XP and Vista will not be available after June 2018
Mozila completely drop firefox for window XP & Vista on june 2018.
When Mozilla released Firefox 53 in April 2017, it no longer supported Windows XP and Windows Vista. Instead, XP and Vista users were moved to the Firefox Extended Support Release (ESR). Firefox ESR is designed for schools, universities, businesses, and others who need help with mass deployments.
Mozilla promised last December to reassess user numbers in mid-2017 and announce a final support end date for the two operating systems. That time, while a bit delayed, has now come.
In August 2016, Mozilla dropped this network support for OS X 10.6 Snow Leopard, OS X 10.7 Lion, and OS X 10.8 Mountain Lion. Unlike Google, which in addition to old OS X releases also dropped Windows XP and Vista support, Mozilla decided to keep supporting older versions of Windows.
Mozilla correctly notes that “unsupported operating systems receive no security updates, have known exploits, and are dangerous for you to use” and it “strongly encourages” users to “upgrade to a version of Windows that is supported by Microsoft.”
The announcement comes after Google who also stopped supporting the two operating systems back in 2016. While users can continue using both Chrome and Firefox, they won’t receive any security support. Microsoft itself also doesn’t offer support to XP and Vista, leaving users on the two operating systems open to security threats. All the browser makers have recommended users to switch to a latest version of Windows to be able to get security updates.
The final end of life date for this network support on Windows XP and Vista. As one of the few browsers that continues to support Windows XP and Vista, Firefox users on these platforms can expect security updates until that date. Users do not need to take additional action to receive those updates.
