I am using firefox 5.0. Windows 7. I left my laptop for a moment then when I get back found it restarted. Since then I can't start firex. Window opens and on the bar is written 'not responding'. I reinstalled the browser, but the problem is there. I checked if windows installed any updates though no new updates. I restarted the laptop many times, but that does not help. What might be the problem?

You might have an add-on that's killing it. Try starting firefox in safe mode. There should be an icon for it in the start menu, or you can open the Run dialogue by pressing Windows key + R and typing
Then disable all add-ons and try starting firefox normally.
