- Adding browser tests to verify correct behavior in integration
- New test that fails on previous version: toolkit/components/antitracking/test/browser/browser_storageAccessScopeSameSiteWrite.js
- Add the ability to store permission by site, use 3rdPartyStorage for this
- No change is made to permission reads. These already proceed recursively, which eventually reach the site.
- When fetching all permissions for a principal, also look for site-scoped permissions on its site's principal
