Firefox 6 keeps crashing

OpenSuse 11.4, 64-bit, using LXDE (but with KDE also installed. The system updated Firefox to version 6 yesterday, but now Firefox keeps crashing. I don’t see anything in any logs, nor is there anything in the ~/.mozilla/firefox/Crash Reports directory. When I restart Firefox, sometimes it asks if I want to restart the lost sessions, sometimes it doesn’t. Sometimes I have Firefox in the background, and I’m not even using it, and it will crash.

Is there some other information I could grab?

Here’s the information from Help–>Troubleshooting Information tab.
