I don't know the improvement of this addon also. Well, it's more colourful, but is it necessary? Ff in it's previous version was stable, I learnd anything about it, so why are new opportunities needed? Don't get me wrong, foxes, but I see the time comming changing my browser. I do need a browser, once configurated, which I can relay on even next year, and I don't want changes for being more competitive to other ones. By the way, how do I realize a downgrade?
