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.

Re: 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 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.

The event viewer shows the following log:

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.
