The descendant of the hugely popular Mozilla Firefox 3.0 used to be called Firefox 3.1, but as the developers have progressed (and what a hard road that was), it was decided that Firefox 3.1 would be called Firefox 3.5 instead.

It’s no secret that the Firefox developers have had a hard time with Firefox 3.1. Now it looks likely that Firefox 3.1 will be released Firefox 3.5 to reflect the significance of the changes that have been made to the browser.

Shiretoko, as Firefox 3.1 is known, includes a number of new features that the developer team says makes it “feel like much more than a small, incremental improvement over Firefox 3″. Among these changes are TraceMonkey, tag and player support, improvements to user controls over data privacy, and significant changes to the web layout and rendering platform.
