Can't wait for the new version of Firefox?
Mozilla plans to officially release Firefox 6 on Tuesday August 16, but a 6.0 version of browser is available for download right now on Mozilla's website.
Firefox 6 is Mozilla's second release under their new rapid release schedule. Mozilla 5 was released on July 21, 2011.
Given the short development cycle, there haven't been that many changes since the last version of Firefox. New features, all of which are listed in Mozilla's release notes, include an address bar that "now highlights the domain of the website you're visiting" and "reduced browser startup time when using Panorama [a tab organization feature]."
As part of Mozilla's rigorous release schedule, new versions of their browser are released every six weeks.
In March, Mozilla's Engineering Director Rob Sayre described the change, writing, "The goal of the process is to provide regular improvements to users without disrupting longer term work." Google's Chrome development team adopted a similar schedule in July 2010.
If you're interested in experiencing the most cutting edge Firefox experiments, before they become beta features, you can visit the Firefox Aurora page to learn more about Mozilla's future release testing. According to Mozilla, Aurora "is focused on delivering performance enhancements and optimizing memory utilization."
