Mozilla updates Firefox to 10.0.1 to fix a bug that “may be potentially exploitable” by attackers. The company rated the bug as “critical,” its highest threat ranking. Mozilla has dealt with crash-causing bugs for the two previous releases as well. Users running Firefox 10 will be automatically offered the 10.1 upgrade. Users can trigger the update by selecting “About Firefox” from the Help menu in Windows or under the Firefox in Mac OS X, or by clicking the update button.”]
