Mozilla will shut down support for its Firefox browser running on Windows XP and Windows Vista in 2017, the company said last week.
The exact timing of Firefox’s retirement from those Microsoft operating systems will be determined in the summer, according to a post to a company blog. “We expect to continue to provide security updates for [Windows XP and Windows Vista] users until September 2017,” the firm said. “In mid-2017, user numbers on Windows XP and Vista will be reassessed and a final support end date will be announced.”
Before that, however, Mozilla will automatically migrate Windows XP and Vista users to the Firefox Extended Support Release (ESR), a build-and-release track designed for enterprises and educational organizations. “In approximately March 2017, Windows XP and Vista users will automatically be moved to the … ESR,” Mozilla said.
