Firefox crashes when any tab in a open window is closed or when i restart the program after taking off toolbars. fix this?

The Firefox program crashes whenever a tab is closed in any window. I tried to solve this problem by disabling my Norton add-on tool bar but the process requires me to restart Firefox. I have tried multiple times but the program crashes instead of restarting so the tool-bar cant be disabled. How can i fix the issue?
