Mozilla revealed it no longer plans to release Firefox 3.7, instead the company will focus on regular features updates for the upcoming version 3.6 of the browser. Originally, version 3.7 should have been released in 2009 but a string of delays to Firefox 3.6 rendered that goal unobtainable. Firefox director Mike Beltnzer claims they learned an awful lot about what slows down their schedule, and that this will help them to plan future releases.
As a result, Firefox 3.7 has been dropped and will be replaced with feature updates for Firefox 3.6 that will be rolled out with security updates. This should free up the team to work on the next major release, Firefox 4, slated for the last quarter of 2010, which is expected to follow the same development process.
The first of the updates for Firefox 3.6 will be the separation of plug-in processes - such as Adobe's Flash - from the browser, which the foundation has been working on as part of its Electrolysis project. A similar technology is used in Google's Chrome, and prevents a single site from crashing the entire browser.
