The Mozilla Foundation Security Advisory describes this flaw as:
Permission prompts for opening external schemes were only shown for `ContentPrincipals` resulting in extensions being able to open them without user interaction via `ExpandedPrincipals`. This could lead to further malicious actions such as downloading files or interacting with software already installed on the system.
