I prefer to use Firefox as my browser. Today i installed an app that made sure you keep the words you had typed out on a message board. I hit the restart Firefox option. It didnt restart. I removed it from the dock, and tried to start it again, all it did was bounce in the dock for a second or two and disappears. I deleted it from my applications and reinstalled it. It still does the same, bouncing in the dock for a few seconds hen disappears. I even restarted my MBP to see if that helped which it didnt. Have you got any ideas on how i can sort this please?
