Firefox won't start. After starting the browser, it shows that it's running in task manger for a while, but then it disappears.
It works in the safe mode with networking though.

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.

I allowed Firefox through Windows Firewall, with no resualts...I going to scan hard disk for malware.
Also try uninstalling Rapport and see if firefox works, if so install it again but remove it from startup/boot.
Great! I've just disabled Rapport and...Firefox turns on. Thanks a lot for the tips.
