This happens with Firefox if it does not like a skin. In order to correct this I usually end up switching to a different skin for FF. I think the cause of this is that the skin was made for an earlier version of Firefox but you have a more updated one that doesn't like it.

I have had that, but only when I have applied a skin and Firefox is running. If I restart it everything is fine.
