Installed Firefox 4.0 yesterday. Last night the header disappeared. Uninstalled, reinstalled. No change. Reverted back to an earlier computer point. Firefox won't open now - and I cannot uninstall.

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.
