Firefox 5.0's UI is nearly identical to Firefox 4.0 but deep down inside Firefox 5.0 is vastly superior to Firefox 4.0 for severa reasons, the most important ones being:

[1] Do Not Track - Firefox 5.0 is the first browser to offer cross-platform support for Do Not Track functionality. It basically inserts special headers into page-loading requests that ask remote sites not to record any personal information about the visitor. However, it's up to the remote sites to actually honor that request.

[2] Bugs - Firefox 5.0 has fixed several stability and security issues, including one in the browser's handling of the WebGL 3-D rendering standard that rival Microsoft has called unsafe.

[3] Critical improvements - Firefox 5.0 has improved support for HTML5, XHR, MathML, SMIL and CSS animations. There are visible performance improvements, including HTTP optimizations and limiting polling frequency of background tabs so scripts there can't drag down the main tab as badly.

[4] Faster - Firefox 5.0 is faster than other browsers and uses very little RAM even with multiple tabs or windows open.

Other improvements in Firefox 5.0 include better spell checking in some languages; improved canvas, JavaScript, memory, and networking performance; better Linux desktop integration; and improved background tab performance.
