Description Huzaifa S. Sidhpurwala 2016-11-15 07:01:44 UTC 
An issue where WebExtensions can use the mozAddonManager API to elevate privilege due to privileged pages being allowed in the permissions list. This allows a malicious extension to then install additional extensions without explicit user permission.
