Upgrade mozilla to version 37.0 or higher.

Overview

Affected versions of this package are vulnerable to Access Restriction Bypass. Mozilla Firefox before 37.0 relies on docshell type information instead of page principal information for Window.webidl access control, which might allow remote attackers to execute arbitrary JavaScript code with chrome privileges via certain content navigation that leverages the reachability of a privileged window with an unintended persistence of access to restricted internal methods.
