From the first beta in July 2010, the latest version of Mozilla’s open-source web browser has been released today.
It boasts an all-new User Interface with previously separate add-ons, now integrated into Firefox 4. Along with the new Gecko 2.0 engine, it also has a new Javascript engine for faster execution. Firefox 4 also supports HTML5 and GPU-acceleration, which lifts the load away from the CPU and lets your Graphical Processing Unit handle it for fast page rendering.
