The 10 Coolest Open Source Applications Of 2010

1. Firefox 4

The first beta of the HTML5-savvy Firefox 4 was released in July. At that time, the code was stable and performance was faster than any version of 3.x we have seen. Now at beta 7, developers have shown performance improvements of as much as five times that of previous betas, and added support for 3D graphics with WebGL, SVG images and backgrounds, and improved form implementation and better JavaScript stability through compartmentalization. Also notable and a first for the Mac OS X version, add-ons for the Apple platform now run out-of-process. This means that, in theory, if a Firefox 4 add-on crashes, it won't cause the whole browser to crash along with it.
