Possible google toolbar and delicious conflict
Installing the torbutton extension caused conflicts with the Google Toolbar, delicious bookmarks, and Adblock Plus extensions.
It caused the delicious toolbar to become blank, rearranged the buttons on the Google toolbar, and removed the buttons added to the main toolbar by Adblock Plus and delicious bookmarks.
Uninstalling torbutton and reinstalling those extensions does not solve the problem.
Using Firefox 3 and Ubuntu Linux.
