Restart in safe mode fixes my problems. How to diagnose the source of the problem?

Drop-down menus do not work. I type and nothing shows in the drop-down list. I select something, and Firefox crashes without showing the selection. If I maximize full page, he says. If I type in the same or another dropdown menu, even when it does not, until I reduce the page.

Restart Firefox in safe MODE and everything works fine. Reboot in normal mode and problems reappear.
How do I diagnose what is causing the problem?

Hi Billamicasr

first try to disable hardware acceleration and check again
