Torbutton prevents GUI customizations in Firefox on Ubuntu
Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:220.127.116.11) Gecko/20100423 Ubuntu/10.04 (lucid) Firefox/3.6.3
After installing torbutton simple GUI modifications disappear (sometimes only on after additional firefox windows are opened). Disabling, or uninstalling, torbutton restores them. See attached JPG screenshot.
EX: By right-clicking on the toolbars in Firefox, and selecting "Customize", I have moved the location of the "Bookmarks Toolbar" to be on the same bar as the File, and Edit menus. I have also added a few other buttons (like open new Window) to be between the URL bar/box and the Search box. After installing torbutton and restarting firefox these disappear. Even if the customizations are added to the new "blank" window, they do not survive for any additional windows or restarting firefox. Only the first window that was launched has the customizations.
Have created new profiles, and the same thing happens even with clean profile, as soon as torbutton is installed. Disabling or uninstalling torbutton restores the customizations.
