A possible cause is security software (firewall) that blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.

Remove all rules for Firefox from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process.

first of all thanx for answering i have even closed the firewall but there is no use and i don't think its a firewall problem as i can run firefox 3.0.1 & ie 6 ,the problem is that the newer versions won't start
