1404359: CVE-2016-9902 Mozilla: Pocket extension does not validate the origin of events (MFSA 2016-94, MFSA 2016-95)

The MITRE CVE dictionary describes this issue as:

The Pocket toolbar button, once activated, listens for events fired from it's own pages but does not verify the origin of incoming events. This allows content from other origins to fire events and inject content and commands into the Pocket context. Note: this issue does not affect users with e10s enabled. This vulnerability affects Firefox ESR < 45.6 and Firefox < 50.1.
