If we want to allow telemetry access, we'll need to limit that down to Mozilla only. I believe Google does this by having an allow list of acceptable add-on ids. There might be a better way, I think Kris has some ideas around this.

Hey Kris - Do you have a strategy in mind for locking down Mozilla-internal APIs? I'd be game to work on a patch, if you're willing to mentor (or can find someone to mentor).

This requires that we start signing system and Test Pilot extensions with special certificates with a particular OU. I don't know how far along that effort is, at this point. Andrew might.

I do and we have regular meetings with Cory and Wil about the signing. We need to get the signing done first then we can proceed on with locking them down. I will ping you on IRC.

That's probably not a huge deal now that legacy add-ons are gone, but I still don't think we want to expose them externally.

You mean if it is in manifest.permissions that it also has to be in manifest.manifest.permissions? I think the chances are slim but some future regression could upset the conditions that cause it to be true but that in that case just throwing here would be better than the alternative (splice()ing the last element off manifest.manifest.permissions!) Are you proposing something different here?

Is this documented anywhere? I can't find it in https://developer.mozilla.org/en-US/Add-ons/WebExtensions/manifest.json/permissions If not, can we get a paragraph somewhere?

I'm not sure that's the right place to document it, that permission is only usable from extensions that are signed as "Mozilla Extensions" and the "Browser Extensions" section on MDN is focused on cross-browser extension standards. Where it covers Firefox-specific features, they are still features that are available to all extensions. If you have an application for this, perhaps we can discuss it via email or IRC?

(In reply to Andrew Swan [:aswan] from comment #18) > If you have an application for this, perhaps we can discuss it via email or > IRC? I'm mainly hoping that folks who want to expose APIs for use by Mozilla WebExtensions won't have to reach out to individual people, and will be able to discover this capability! We have some specific experimentation/future work desires around storage and sync, but it would be awesome if I could point engineers to docs rather than people. Is that a realistic expectation, or is this something we intentionally want to limit awareness of within Mozilla?
Is manual testing required on this bug? If Yes, please provide some STR and the proper webextension(if required), if No set the “qe-verify-“ flag.
