My Favs include: 1) NoScript 2) AdBlocker 3) Filterset G for AdBlocker 4) Download helper 5) Download StatusBar 6) FireFTP 7) Flashgot 8) IEtab (to see how IE renders in firefox)

I read how some ad supported sites are trying to drop any firefox support because of adblocker. What good it it if we use the IE-tab, NoScript and Adblocker. We still have all we need!!
