After exiting Firefox, if I try to go back in, it says that Firefox is running, but not responding, and I have to go into Task Manager and close the process for it to work again. This problem isn't fixed by restarting my computer.

You should see Firefox hangs or is not responding - How to fix. The section "Hangs at exit" should solve your problem
