Recently upgraded to FF4 because 3 was messing me around - despite how much I love it :(

The one thing that's irritating me is a lot of old plugins don't work in the new version. Tried a few different versions I could find on greasemonkey etc and the irritating part is they work but don't actually load any servers (it just shows up one server with 0/250 players on a FFA map with no name - rather odd)

Anyone using Firefox 4 with some useful plugins? Mainly looking for an alternative server browser for QuakeLive but anything else would be gravy
