This is on an otherwise (mostly) idle system. Unfortunately it seems to be interpreted JavaScript code causing this, which is doing something with SQLite.

How can I expose Firefox Chrome JS symbols to the profiler?

This is a mass search for bugs which are in the Firefox General component, are
UNCO, have not been changed for 500 days and have an unspecified version. 

Reporter, can you please update to Firefox 3.6.10 or later, create a fresh profile, http://support.mozilla.com/en-US/kb/managing+profiles, and test again. If you still see the issue, please update this bug. If the issue is gone, please set the status to RESOLVED > WORKSFORME.
