When i start Firefox it either 1) crashes, no crash message displayed. just closes as if nothing happened. 2) freezes, doesn't respond to anything and i have to "kill" it with task manager because if it froze and i try to click elsewhere like to show desktop or on another task it freezes the entire computer. It freezes in 3 ways: 1) is when i just opened it and it freezes immediately 2) when i click on it, or start typing some address into the bar 3) when i press enter after I've typed the URL in the address bar. my Firefox doesn't have any add-ons, or anything else. i already re-installed it 2 times, cleared cache, history, reset all settings. still crashes
