When I exit Firefox, it will not start again using the icon or a link within an e-mail message. To fix this problem, I have to open the Task Manager (CTRL + ALT + DEL) select the Processes tab, select firefox.exe instances (always one, sometimes two) and press "End Process" button. Then Firefox will open from its icon or a link.

Why is this happening and how so I prevent it from occurring?

Sounds like it is hanging when you exit and later try to restart Firefox.
