if you have access to their project tracking, it's under WEBEXT-1351 (would love if someone can post the entire reasoning for the feature here, as their conversations are now behind login which i didn't bother to secure)

The code for what the user can see/allow per-domain https://hg.mozilla.org/mozilla-central/rev/4399291987d9 (not released as far as i can tell) you can see the file locally via `resource://gre/modules/ExtensionPermissions.sys.mjs` in your address bar.

and lastly, the dev doc on how to push those values to live user browsers https://firefox-source-docs.mozilla.org/toolkit/mozapps/exte...

this is already how it works on Firefox for android, with NO USER WHITELIST OPTION... the only workaround on android is to add another hidden setting that points to a user-defined collection in addons.mozilla.org, which will be the allowed extension list instead of mozilla's.

edit; HOLY SHIT!!! just updated firefox for android, and they removed access to about:config there in the last version! (ps: they had already removed since 2020 for "regular lowly users" who do not install experimental version, their words. Now it is also removed from f-droid stable build since last version. I didn't see it mentioned on the release notes, so they either strong armed the maintainer or slipped changes past them)
