This may be extension related (Score 4, Insightful)

My coworker and I just upgraded to 1.0 and have bothed noticed that firefox will eventually eat up most/all system memory, forcing us to kill firefox and restart it. (we ran the beta/pre releases with no issues) The only common factor is that we both had to reinstall the web developer (version .8?) after upgrading to FF1.0.... Could this problem be related to specific extensions and not specifically to firefox itself?
