I just upgraded from Fedora 10 to 12. I like it a lot, but there's a minor issue with my chosen eye candy. I changed the default mouse pointer theme, but it reverts to Bluecurve while the cursor is in Firefox. I've tried renaming the theme default and putting it in ~/.icons/default and making the index.theme file point to the theme directory in /usr/share/icons but it still does the same thing.
So basically, waaa my mouse isn't pretty while web browsing. Waaa waaaa!
