Comment 1 for bug 322414

I have the same problem, except I'm using Ubuntu 8.04. A few days ago Firefox 3.0.5 lost all bookmarks, there's no back, forward reload or stop buttons (all greyed out, and using the alt + arrow keys is also disabled). Today Ubuntu updated Firefox to 3.0.6, but to no avail - nothing has changed. Other errors include disabled "Open links in new window" (opening them in a new tab seems to work, though), and a constant page loading turning wheel symbol in the tabs - but no animated symbol in the main window at all.
