firefox will not load, but shows in task manager

more options

Sometimes when I try to open firefox the program will not open, but it appears in task manager. I can end process, sometimes I can open then and other times it will not open. Then I have to reboot for it to open. I was using ver 36.0.0.4 then upgraded to 37 with no change. I went back to ver 28 and tried it and it worked, but I did not try that many times. It will work for 4 or 5 times then stop working and I have to reboot. I am using windows 7 32 bit.
