I installed firefox 4 thinking it was an upgrade, but it crashes all the time. Even typing firefox 4 crashes into the search bar without even searching crashes the new browser. Sometimes when it has not crashed, you cannot even type into the search bar. Browsing in general in firefox 4 is guaranteed to crash every 15 to 20 seconds. I read somewhere to turn off hardware acceleration and turn off all plugins might help, but no matter what it just crashes constantly. Is there anything thing else I can try. I never had any problems with firefox 3.
