What the hell is it with program designers these days with removing functionality and jamming every single option left into a single button? I just spent the last hour setting Firefox back up to something approaching what it looked like before I updated it to version 4, and there is still just a bit too empty space up top for my liking.
Once I got the menu situation sorted, I had to track down a way to rid of the annoying link bar that pops up whenever you scroll over a link. Why they decided to completely remove the status bar I have no idea, but you can at least get some that functionality back by installing the Status-4-Evar plug in. Installing that gives the pop up link bar a new home (no more popping up), or it can be disabled completely if you don't want to look at it all.
The only good thing so far that I've found with the new version is that it remembered my Awesome bar setting to never, ever show up under any circumstances. They claim that it's faster than the old version, but if it is, it's such a small increase as to be nearly undetectable.
