I don't believe anything he said after reading that.

BTW, I'm not having any cpu utilization problems with FF2.x. But I don't run things like forecastfox or anything else that does anything in the background that could increase cpu utilitzation when I don't need it. I have Fasterfox, fireftp, flashblock, flashgot and linkification installed. (in addition to talkbalk and Dom Inspector.) I don't enable the cache-ahead features in fasterfox.

There's probably a memory leak in 2.x. I'm sure it will be plugged eventually. If you want to reclaim the leaked memory, you have to completely restart ff. If you have enough memory in your system, it probably doesn't matter. If you run taskmgr and look at the performance pane, if your peak commit charge is greater than the amount of physical memory you have installed, then you could benefit from more memory, or perhaps by restarting ff.
