No Going Back Now Puntuado con 5 de 5 estrellas
Internet without this add-on is dead to me, just like Fredo in the Godfather II.
In fact, I'm refusing to use my firefox 3b5 until there's an update for it.
If you have FF 2 or FF 3b4 and don't have this add-on, download it immediately, even if beloved family members are having medical emergencies. Grandma can always get a blood transfusion, but you NEED this add-on.
