This Beta includes performance enhancements that improve the browsing experience for users and enable developers to create faster web apps and websites. The latest Mozilla Firefox Beta is now available for testing on Windows, Mac, Linux and Android.

The non-profit organization has promised to push out a new stable build every six weeks.

Other improvements and changes in Firefox 43 include support for more intensive content-and-ad-tracker blocking using 'lists' from San Francisco-based Disconnect, which also powers the 'Private Browsing' mode introduced last month with Firefox 42.įirefox 43 beefs up the browser's built-in blocking of ad trackers, but the big news is the appearance of a 64-bit version for Windows, a project years in the making.įirefox 43, including the 64-bit version for Windows, can be downloaded from Mozilla's website.Mozilla has switched Firefox to a rapid release development cycle which means new versions will come more frequently. Although Mozilla has long had 64-bit versions for OS X and Linux, the developer shelved work on one for Windows in November 2012, only to recant and restart the project a month later.Ī 64-bit Firefox was important for Mozilla if only because of its push to retain users switching to Windows 10, which like previous editions of Microsoft's OS, comes in 32- or 64-bit versions. Its path to a 64-bit Firefox for Windows has been contorted. Mozilla was the last holdout among the top five browser builders. Opera Software, the Norwegian browser maker known for its same-named desktop flagship, also offers a 64-bit edition on Windows. Google, for example, shipped a Windows 64-bit Chrome in August 2014 and one for OS X in November of that year, while Apple's Safari and Microsoft's Internet Explorer (IE) have had 64-bit editions on OS X and Windows since 20, respectively. The appearance today of the Firefox 43 ends Mozilla's climb to catch up with rivals, who had offered 64-bit browsers long before, in some instances years. The biggest advantage of a 64-bit browser on a 64-bit operating system - like Windows and Apple's OS X - is that it can address more than the 4GB of memory available to a 32-bit application, letting users keep open hundreds of tabs, and run larger, more sophisticated Web apps, notably games.
