Since I have installed Firefox 8.01 I can't open it anymore, even after I uninstalled it and reinstalled it (both in the US & the German version). What to do?

Even upgrading to the beta of Firefox 9.0 did not remedy this.

See:

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 and the updater process.
