If it helps, I was going to report a bug exactly the same as this, but updated some extension and it stopped occurring.
When I was typing the bug report I went to check on my extensions to list them in the report. I noticed the Gmail Notifier and Google Gears extensions needed to be updated from my prior upgrade to Firefox 3.0.1. After I performed the updates and restarted, this bug went away. It is probably worth noting that Gears was disabled for being incompatible but the Gmail notifier was still enabled, but just out of date.
