Sorry, the main process goes to 140%, and about 5 more other firefox processes start chewing up 80% cpu each. I just added them altogether. I have seen it spike to 400% a few times in activity monitor. As to what I'm doing, open up say lobsters, click on all the tabs that look interesting, forget them for a day, repeat. End of the week have a look see at things.
