Mike, how do you feel about priority here? Is this easy to fix? webextensions don't have access to file:///, and I don't know how easy it is to specify an actor match pattern here that does include files...

Flags: needinfo?(mconley)

ActorManagerChild does its matching using the same logic as the WebExtension URL matcher, but I believe has a broader range of schemes it will allow by default. I believe file:// is one of them.

So, I think we can just add file:// to this list:, and this will work again.

Priority: -- → P5

Firefox version 70 is still affected.
