Mac OS 10.6.7 I can't install Firefox 4 because the alert screen says "The operation can't be completed because you don't have permission to access some of the items" even though all my plug ins are up to date. Help!
When I try to install Firefox 4, it gave me the message above and also broke Firefox 3.6.17 that I had installed. I have since reinstalled 3.6.17.

I removed all firefox apps and started over with 4.0. Now it's working.
