Windows: Firefox has been available in unofficial and testing 64-bit builds for years, but this week, Mozilla finally released an official 64-bit version of Firefox for Windows 7 and above.
Along with the other minor changes in Firefox 43, you’ll also find new versions of Firefox on the download page (you have to re-download it from Mozilla; upgrading won’t get you the 64-bit version). Note that it doesn’t have support for many plugins, because Firefox is phasing out support for NPAPI plugins by the end of 2016—so if you still rely on any of those, you may want to stick to 32-bit for now. But, if you’re on a 64-bit system, you may see some performance improvements with the new version.

Firefox 64-bit for Windows Now Available
By Vygantas | December 16, 2015 Grab it now.
With the recent release of Firefox 43, Mozilla has finally introduced the stable 64-bit build for Windows users, something we have been waiting for almost a decade.
In case you forgot, Mozilla has abandoned the 64-bit builds back in 2012 due to the “significant negative feedback” only to change their minds afterwards.
As far as Firefox 43 features go, it includes Private Browsing with Tracking Protection that allows users to choose additional blocking trackers, search suggestions selection from the Awesome Bar, on-screen keyword on selected input fields, various security fixes and changes for developers.

Congrats to Mozilla for reaching a significant milestone.
