When I upgraded to latest version of Firefox, the logo disappeared in dock and is replaced with some generic version (i.e. white page with Application "A"). The logo still shows up when I view FF in the Applications folder. I've tried dragging and dropping it back in the dock (from applications folder to the dock) but it didn't work. Still just generic logo. Firefox opens and seems to run fine... but I would like to see the logo back. Any suggestions?
