I forgot to mention in Comment #1
Set browser.allTabs.previews to true in step 1.

I think I'm pretty sure that it was caused by an addon as it went away. I think it was the Zynga Toolbar. As it uses some kind of addon kit, I guess there are other addons that cause the same problem.

This bug has had the CLOSEME tag for several weeks and the date in the tag is far gone. If the reporter can still see this issue, Please retest with Firefox 3.6.x or later and a new profile (http://support.mozilla.com/kb/Managing+profiles). Then please remove the closeme tag in the whiteboard, mark the bug against the proper version and comment on the bug.
