When I updated to precise about 10 days ago I ran into a similar problem. Upgrading to version 17 of the mozilla products seems to have had a positive impact.

Just over the last few days, if I start Thunderbird as soon as I've logged into Precise, xorg starts hogging CPU. Top shows over 90% in use, and the system becomes very sluggish. The only cure seems to be either rebooting or (simpler) logging out and in again. Sometimes I have to kill the Xserver instead of logging out. Waiting for a little while (say, a minute) before launching Thunderbird seems to solve the problem.
