firefox is not starting on my service pack 3 xp system, suddenly it stopped working and i have tried some suggestion provided by you for similar problems like restarting, uninstalling, some changes being made by bringing the system in safe mode with networking, which were suggested to other people with similar problems but nothing helped.

Did Firefox update to 27.0.1?

It is possible that your security software (firewall, anti-virus) 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 and the plugin-container 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 and the updater process.
