Hi Liowal & welcome.

Did you look in the Processes tab (Ctrl+Shift+Esc) of the Task Manager for the firefox.exe process? It has been known for more than one process to run.

If you are running more than one version of Firefox, ie Minefield or Bon Echo also, they all use the same firefox.exe process, that's why it needs to be closed (End Task) before restarting.

Having said that, it does sound like you may have problem(s) with your profile, but we'll go there when/if you get re-started.
