What is the cookie "about.ef2a7dd5-93bc-417f-a698-142c3116864f.mozilla" and why I can't delete it?

That is about first party isolation (firstPartyDomain) for about pages (see: about:about) and isn't a real cookie.

  1. define ABOUT_URI_FIRST_PARTY_DOMAIN "about.ef2a7dd5-93bc-417f-a698-142c3116864f.mozilla"
