Firefox Icons greyed out in safe-mode

[AndyWLUG]

Binary package hint: firefox-3.0

When I type "firefox --safe-mode" in the konsole, the Firefox GUI comes up, but the icons for reload, stop, back, forward are greyed out and don't do anything when I click on them. Also, I can type a URL into the text box, but when I hit enter, the browser does not go to any website...its as though my keyboard input is being ignored, but it is echoed on the screen.

If I Edit->Preferences and enter a URL for home, and then click the Home icon, it does not go to that URL, but instead to a Mozilla related website.

This is true in some accounts on my computer. In other accounts on the same computer, Firefox works fine.

Yes, I tried moving the entire ~/.mozilla directory tree out of the way, to no avail.

This is on Kubuntu 9.04 with firefox 3.0.14.

firefox-3.0:
  Installed: 3.0.14+build2+nobinonly-0ubuntu0.9.04.1
  Candidate: 3.0.14+build2+nobinonly-0ubuntu0.9.04.1

Thanks in advance for your help!
