I'm going to assume that you know very little about Firefox's development process (and the software development process in general).
Most notably, an official 64-bit version is planned (you can grab 5.0a1 64-bit windows off of their servers).
Firefox 5 fixes a few UI issues that 4 didn't quite do right, makes things more intuitive, and essentially tries to draw in those who decided to stick with Fx 3.x.
It is also going to bring a new account manager (due to the current one being pretty lacking, especially if you have multiple accounts for the same website, etc.)
The reason for the switch is because it took Firefox 4 almost a YEAR to be released. The issue with this is that it took that much longer for users to have all of the new things that they created over that time such as:
-new tab data structure for faster tab switching
-new HTML rendering engine
-new database structure for storing user profile information
Do you see how these features could have easily been split into two or three separate firefox releases?
