Mozilla is now offering the 64-bit version of Firefox the default version for users of 64-bit Windows. This is a move that has been a long time coming as 64-bit Windows users got the 32-bit version of Firefox by default. And previously you needed to jump through hoops to get the 64-bit version of the browser. The 64-bit version of Firefox offers more security and improved performance. Another advantage of running the 64-bit version is it can access more than 2 GB of RAM which, if your PC has adequate RAM, will reduce the number of browser crashes.
To view the version of Firefox that’s installed on your system, go to Help > About Firefox on the Menu bar.
How to Get 64-bit Firefox for Windows
If you’re running 64-bit Windows, there are two ways to get the 64-bit version of Firefox. The first way is to download a fresh copy of Firefox and install it. That will automatically give you the 64-bit version which is now the default. It’s important to note that if you go this route, the 64-bit version will not replace the 32-bit (x86) version. So, to avoid confusion you’ll want to manually uninstall the 32-bit (x86) version for best results.
The other option you have is to just wait. According to the announcement from Mozilla, the company says it will migrate 64-bit Windows users to the 64-bit version of Firefox in an upcoming update. However, the company hasn’t specified when that update will be released. After you are migrated to the 64-bit version, Mozilla says you can get back to the 32-bit version by re-running the 32-bit installer from the Firefox platforms and languages page.
