I agree. Stability in Firefox 2 is significantly worse than 1.x. I have to restart it at least once every couple of days, and frequently have to wait 20-30 seconds for random things to complete, during which it is completely unresponsive. If 3 beta is even slightly less stable (which would make sense) then I'll wait a while. Hopefully those issues will be resolved.

Firefox 2 being unstable is all the more reason to try Firefox 3! A lot of the instability comes from the Firefox 2 rendering engine breaking down when you have Gmail and Google Docs and Meebo and 12 Youtube videos open at once. Firefox 3 is using 230 megs of RAM for me right now. If I was running Firefox 2 with the same tabs it would be moving at a crawl and using 750 megs of RAM.

The bug I notice the most is text entry/dropdown boxes sometimes not working correctly, this happens most often in a really poorly programmed game I play, http://www.hyperiums.com.
