When I close Firefox it will not open another window when you click on icons or manually try to open new window. I have to open Task Manager find Firefox program and manually close program. Then when you open a new Firefox window it try's to restore previous session , saying sorry Firefox crashed. I have uninstalled and reinstalled , turned off all add-on's nothing has worked. No virus's , no other outside influences , nothing else on my computer has issues. Can you help?
