Forget Microsoft and the dull facts of its still dominant market share - Mozilla is really the biggest name in browsers.

OK, so Internet Explorer may still be top, but Firefox was the first to really make a dent in Microsoft's market share and with version 3.5 it's still pushing the boat out.

Since Firefox 3.0 was launched, Mozilla has fresh competition snapping at its heels from the likes of Google's Chrome, Apple's Safari 4 and let's not forget Opera, with its recent 10 beta. All have touted speed improvements for general rendering and JavaScript.
