OK I can see the edit, quote, and other buttons while using IE9. Been awhile since I have used IE. In Firefox the buttons disappear. Even with Adblock disabled the buttons still do not appear.
Well there you have it. Following your kind of reasoning/comments one would have to now conclude that Firefox sucks..........
EDIT:
For the record. On my PC machines I have always used IE and nothing but. On my various iDevices only Safari. Firewho?.......bah.......hehe
