Starts fine and grows slower and slower with use until it stalls, freezes, etc. Affected by javascript loaders that load columns of ads, etc., or at least it seems that way. This behavior on 4 different computers from windows xp to vista to windows 7 with different sets of addons and no addons.

(Mac=Options)
key, and then starting Firefox. Is the problem still there?
