Hi Druzion,

Could you please attach a minimal testcase so I can test this on my end ?

Thank you.

Attached simple example. Once installed, you have to wait a few seconds for the error to be logged, and Firefox sometimes shows "(unknown)" as the source of the error.

I've managed to install the test extension you provided, but the browser console throws a lot of errors (see attachment) and I'm at a loss how exactly I should open a page from the extension.

Those errors are just ones that have accumulated while browsing the internet. Just before you install the extension, clear the Browser Console. Then install the extension and you will see the error.

Hi Ben, do we have any plans yet to support moz-extension protocol?

Comment 7

[Ben Kelly [:bkelly, not reviewing]]

Don't extensions have their own way to handle network interceptions?  Currently we have no plans to allow this.

According to comment 7, I tend to close this as WONTFIX for now. 

Hi Reporter, 
If you have a specific extension use case that the current extension interception method cannot fulfill your need, you may consider filing a bug under the product/component - Toolkit/WebExtensions:Untriaged - to get right people's attention.
