Noticed this after I upgraded to Firefox 3.6. The bottom error pops up in the Firebug console after every navigation, both errors appear when clearing the history.
Disabled all plugins except FlashGot and Firebug to verify that FlashGot was the source of the errors.

Confirmed. Should be innocuous, thought.
Will be fixed in next release.

Fixed in latest development build

Big thanks for the fix.

I noticed the error in the Firebug console before I upgraded to Firefox 3.6. Indeed to get rid of this error information I decided not to wait till all my extensions were updated. And same as before.

Finally I managed to find here the solution. So I don't have to wait for the official release. THX.
