Mozilla does not expect to release the next major upgrade of Firefox for at least 12 months, according to a new product roadmap.

The report details that Firefox 4.0 is due to arrive in either October or November of 2010 and will bring with it a range of new features, such as a new slick user interface and multi-touch gesture suppport.

Firefox users can expect a number of changes before the release date of 4.0, with versions 3.6 and 3.7 lined up for release. These will offer such improvements and features as faster javascript handling, improved form completion tools, bookmark synchronisation and pageload enhancements.

Mozilla also revealed that when Firefox 4.0 does launch, it will follow Google Chrome, with each tab functioning as its own separate process, reducing the instances of lost browser sessions.
