Firefox won't open when clicked on.

When I click on Firefox, the blue circle spins but the browser never opens. When I watch the running processes on the task manager, firefox.exe pops up after I click the applications, but goes away after a few seconds. I've tried unistalling/re-installing with no luck. I've tried to run the profile manager from the command line, but again, the blue circle spins, then nothing happens. I have tried to hold down the shift key and start in safe mode, but no prompt ever appears to reset/start in safe mode. Not sure what to do now...

Start Firefox in Safe Mode {web Link} by holding down the <Shift>
(Mac Options)
key, and then starting Firefox. Is the problem still there?

While in Safe Mode;

Type about:preferences#advanced<Enter> in the address bar.

Under Advanced, Select Network. Look for Configure How Firefox Connects and press the Settings button. If you are using a proxy, make sure those settings are correct. If there is no proxy, first use No Proxy. If there is a problem, then try System Proxy.
