I find that it is still unstable. Running on windows even the latest version (3.0.1 I think it is) still crashes now and again, and running under Linux it seems to have some memory leak issues. I had to take it off an old laptop I was running it on because of constant crashes. The laptop is now running version 2 fine. Firefox is also getting much more bloated with every new release, and I only run about 3 add-ons. I may end up going back to version 2 or going back to Opera which I have always had installed but don't use that often.
