Mozilla, however, promises to address this in the coming updates. While Firefox 64-bit comes on Windows with improved security and speed because it can access new technologies that are exclusively available on this OS version, it's worth mentioning that some plugins are not yet supported. Mozilla then promised to release Firefox 64-bit on Windows nearly one year ago, but the application has only made it to the Developer channel earlier this year. In fact, Mozilla also planned to abandon the project and in November 2012, it discontinued the 64-bit version of the browser for Windows.

Important milestoneĪlthough a 64-bit version of Firefox has been available on Linux and Mac OS X for many years, Windows users have never received more than a Nightly build, which was obviously more or less unstable and buggy.

Unfortunately for those on Windows XP, Firefox 64-bit does not support this OS.

The 64-bit build for Windows comes with support for Windows 7 and newer, including Windows 10, so the majority of users are supposed to be able to run it. After so many years of work, the 64-bit version of Mozilla Firefox is finally available for download for Windows users too, promising increased speed and better security.įirst and foremost, it's worth noting that this new version arrives as part of branch 43, which was officially released on all supported platforms only a few minutes ago.
