Mozilla has released version 3.6 of the Firefox browser, which addresses a number of bugs and adds some new features to the browser. In addition, it refines the code, bringing about a 20 percent increase in speed over the prior version of the browser.
Lastly, they have added a new feature called "Personas", which make it easy to apply new themes and other appearance attributes with a single click. While more aesthetic than functionally significant, people who like customizing their browser may find Personas to be rather appealing.
This is the last expected full version update to Firefox for some time to come, since Mozilla has changed their development schedule and has removed Firefox 3.7 from its expected release date sometime in the second quarter of this year. The next Firefox release should be expected sometime later this year, or even next year. Meanwhile, Mozilla will continue to release updates to Firefox 3.6 as is needed.
