Mozilla has switched Firefox to a rapid release development cycle which means new versions will come more frequently. The non-profit organization has promised to push out a new stable build every six weeks.
The latest Mozilla Firefox Beta is now available for testing on Windows, Mac, Linux and Android. This Beta includes performance enhancements that improve the browsing experience for users and enable developers to create faster web apps and websites.
Firefox Beta gets updated several times per week and as a consequence, the release notes for the Beta channel are updated continuously to reflect features that have reached sufficient maturity to benefit from community feedback and bug reports.
In addition to these release notes, you can follow ongoing development on our @FirefoxBeta Twitter account.
