Just installed Firefox to Mac OSX 10.7.5. FF opens ok, but within seconds, a small white box drops down from the top of the window, the "File/Edit/View/History etc" from the top of my screen disappears leaving only "FireFox" and my Apple logo in the top left corner, and FF remains frozen. I can quit it and restart, but it just keeps happening. I have uninstalled and reinstalled, and it keeps happening. Any ideas?

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).

  • Do not click the Reset button on the Safe mode start window or otherwise make changes.
