After months of beta testing, Mozilla has released a 64-bit version of its popular Firefox web browser for Windows. The new version was included in the recently released Firefox 43 build and is designed to work with Windows 7, 8, 8.1 and Windows 10 in their 64-bit SKUs.
The new version is available from Mozilla's download page for Firefox, and can be accessed when users click on a Windows logo with the "64" number on that page. As PCWorld notes, people who have the 64-bit version of Windows installed should be able to keep more tabs open with the 64-bit version of Firefox, and run some web apps that require 64-bit support. Also, the new browser version should be able to address more than 4GB of memory, if available. The downside is that some web plugins are not compatible with the 64-bit version of Firefox.
That being said, it's great that Mozilla finally has a 64-bit version of Firefox for Windows users, especially since the vast majority of Windows systems are now using the 64-bit option.
