Firefox is one of the most heartening of success stories of open source, up there with MySQL and Apache. It has managed to break Internet Explorer’s synonymy of Internet with Internet Explorer. So when Mozilla shares details of any new version, it is bound to be something exciting.

Of late, Firefox has fallen behind in speed with Google Chrome 6, Safari 4 and Opera 10.6 taking the lead. Being far ahead of IE8 is no consolation, and with IE9 posting slightly better scores in JavaScripts tests than Firefox 3.6, Mozilla has reason to worry. The good thing is that Mozilla is already working its way to the top.

Firefox 4

While one may argue that increasing the speed of the browser beyond a point doesn’t help, it is clearly what the future lies. Mozilla knows this and is already working on a new JavaScript Engine, JagerMonkey which takes the best features of Firefox’s TraceMonkey and WebKit’s Nitro Engine to create an uberfast JavaScript Engine.

Firefox 4 will also place an emphasis on reducing the chrome of the browser (The UI Elements) slimming down the browser to a more Google Chrome like look. Firefox 4 will have a completely new visual look, one which makes ample use of Windows Vista and 7′s Aero effects.

Firefox 4 will also have some amazing new features such as Application Tabs (which will work like Chrome pinned tabs), a new addon manager, integrated developer tools and better HTML5 support.

Those waiting for Firefox 3.7, there are both good news and bad. While Firefox 3.7 will be dropped in favor of Firefox 4 (Currently in Beta 1 stage), out-of-process plugins, one of the most awaited features of Firefox 3.7 will come with 3.6.8 due shortly. Out of Process plugins stabilize the browser, ensuring that it doesn’t crash even if a plugin crashes.
