I love ff but hate ff4 for 1.removing the rss button from the address bar 2.my installation crashes several times a day due to: EXC_BAD_ACCESS / KERN_PROTECTION_FAILURE 3.certain flash ads play out of order or appear in the wrong ad spot! I've never seen anything like this on another browser except ff4 im on mac osx snowleopard btw.
