I installed Firefox on my Mac today (Mac OS 10.5.8) However File>New does not open browser window. Nothing happens. I rebooted and launced Firefox again but this did not help. I had been using Safari. Firefox is clearly running and I must do a "Force Quit" to quit Firefox.

This happened

Every time Firefox opened

I installed Firefox on my Mac today.

Ok, I have the answer dear Mac friends.

Go to your finder window - then at the bottom - include system files.

Search for firefox - delete everything - reinstall. Problem solved.
