What theme is causing the problem?

I am not able to reset to default firefox theme

Are you prevented from changing the theme? Please explain.

Start Firefox in Safe Mode {web Link} by holding down the <Shift>
(Mac=Options)
key, and then starting Firefox. A small dialog should appear. Click Start In Safe Mode (not Refresh).

Is the problem still there?
