Multiple Mozilla products contain a flaw that is triggered when an error occurs during the handling of OnLocationChange events. This will cause SSL certificate information from a previous site to be displayed on the address bar.

Upgrade Firefox to version 15 or higher (10.0.7 for ESR) or SeaMonkey to version 2.12 or higher, as they have been reported to fix this vulnerability. An upgrade is required as there are no known workarounds.
