I'm running a Mac OS X Version 10.4.11 Just updated to Firefox 4.0 after Yahoo advised that things would run better. Upgraded from Firefox 3.1.16 (I think) I cannot open the Firefox browser at won't let me launch the browser. It says: "You cannot open the application "Firefox" because it is not supported on this system". How do I go back to the old version? least I was able to launch it and use it? Any help would be appreciated. Posted: Fri 06May2011
