Mozilla has reiterated that since the 64-bit version of Firefox for Windows offers limited support for plugins now, some websites - that need plugins - will be incompatible on the new browser. The 64-bit version is available for Windows 7, Windows 8, Windows 8.1 and Windows 10 and can be downloaded from Mozilla.org. While the update to Firefox 43 is primarily targeted towards 64-bit Windows users, the update also improves the experience on 32-bit systems.

A preview version of the 64-bit Firefox browser for Windows was released way back in March.

Firstly, here is what is new: Private Browsing with Tracking Protection will now offer the user a choice of blocking additional trackers, API now has improved support for support for m4v video playback. The rollout of 64-bit Firefox version for Windows PCs comes as a result of Mozilla's recent update to Firefox 43.

In the past, several attempts have been made, officially, and unofficially, along with alpha, and beta builds to structure the 64-bit version of Firefox on Windows, although none of them could go through. Most of the big improvements happen behind the scenes, although the 64-bit version should be able to keep more tabs open without slowing as well as run web apps that require 64-bit support. The outgoing 32-bit version of Firefox can only use 4GB of address space which although "good enough" for most applications can't handle large Web applications as effortlessly as the 64-bit version.

The one thing you will notice is that some plugins simply won't work with Firefox's 64-bit version. This is ahead of the plan to remove all NPAPI plug-ins from Firefox by the end of 2016.
