Today we are releasing Firefox 64-bit for Windows to offer gains in performance for users with 64-bit systems. We’re pleased to offer it to users of Windows 7 and above looking for added performance for applications and games.
Firefox 64-bit for Windows, by design, has limited support for plugins and users will notice that certain sites requiring plugins that worked in previous 32-bit versions of Firefox might not work in this 64-bit version. As we’ve shared previously, Mozilla intends to remove support for most NPAPI plugins in Firefox by the end of 2016.
To download and install Firefox 64-bit for Windows go to the Firefox All Systems page.
We’re counting on your feedback to continue improving Firefox with 64-bit support.
