I recently updated to Mac OS 10.6.5 so Firefox will not quit (unless forced to quit), and I get the following error message. "The application Firefox.app can't be opened -600." Same problem with Safari, Google Earth, I-Tunes, and Adobe Acrobat Reader.
I have to actually force quit these applications for this to work. How do I fix this. I also upgraded to Firefox 3.6.13.
