MacBook Pro can't open in Firefox, always goes to Safari
I have a MacBook Pro - OS X, 10.8.2, and want the default browser to be Firefox, not Safari.
The consistent advice is: Safari/Preferences/General and showing Firefox as the default browser. I have done this, and when I start up I keep getting Safari, not Firefox. I can then click on Firefox from the Launchpad and it comes up and works fine; I would just like to avoid the extra steps I take to quit Safari and start Firefox.
The Apple representative with whom I spoke took me through the above steps and was baffled that it didn't work. She suggested that I contact Firefox, so that's what I am doing. Please help. There must be some setting I have inadvertently done to myself.
