    Firefox 4 beta brought me back into the fold, but that’s about to change real quick. I can’t stream videos from netflix with it and now my bookmark toolbar has disappeared and I can’t seem to get it back. The hand dandy help menu shows you what you need to do in 3.6…

    Sorry, Mozilla – you got axed for the last time.
