I changed my preferences and now Firefox crashes my computer when I open it-why?

I changed some preferences (including the clear browsing history, cookies, cache, etc. When you exit firefox) and it freezes. When I forst wuit firefox after changing these settings, it took more than 10 minutes (rotation of the wheel) and I finally forced to quit. so when I have opened firefox, everything on my computer before upward. I could not even rule out the window or select 'force quite. ' I had to stop hard. When I rebooted my computer, I opened safari first, then firefox. When firefox open he did the same thing - everything froze, could not move the window, etc. - except this time I clicked on the safari icon and then was able to navigate to a force quite on firefox. How to solve this problem? I hate safari and you want to resume as soon as possible by using firefox. Thank you!
