Firefox will not run on my Mac Mini running Mountain Lion 10.8. When I start the program there is no response or activity for several minutes. Then after several minutes, Firefox opens but there is no response after that. I've uninstalled Firefox by moving the icon in the Applications folder to the trash and then re-installed it. That does not resolve the issue. I've also uninstalled it by moving the icon from the Applications folder to the trash and deleting the Firefox folder located in the application support folder which is in the library folder. Several sites including the Mozilla site refer to the latter method as a complete uninstall. That did not resolve the issue either. Does anyone know how I might fix this? Thanks.
