Firefox 1.0 CPU Usage

Just a quick tip—if you’re having problems with FireFox using an excessive amount of CPU time, be sure to check your extensions…

On my G4/1.5GHz PowerBook, I’d noticed FireFox 1.0 was starting to take 35% - 45% of the CPU, even when it was running in the background.  I went in and removed a few non-critical extensions (GCache, FoxyTunes) and disabled a couple of others (Search Status (shows pagerank)) and Tweak Network Settings), and CPU usage fell back to a reasonable 2% - 8%.  I don’t have the time right now to narrow down which particular extension or combination of extensions might be causing the problem, but if you’re seeing problems, you might want to go in and carefully start disabling a few extensions…
