But 300MB+ memory usage? And 50% CPU usage?? And even filling a simple form got too slow.
Then I remembered reading quite a long while ago (Firefox 1.0 days) that some of the firefox extensions can be problematic and cause memory issues with firefox. I did install quite a few extensions so I decided to take a look.
Here is the Mozilla Page which list all the problematic extensions. In my case, it was Cooliris that was causing trouble. I disabled it, and my firefox is up working again.
