Firefox is releasing a pretty aggressive tracking block with ETP 2.0 https://blog.mozilla.org/security/2020/08/04/firefox-79-includes-protections-against-redirect-tracki...
From what I gather, they will eliminate all tracking cookies every 24hs. I highly suspect this will also affect any Adobe cookie, regardless if they are first-party or third-party.
"When you first visit a redirect tracker it can store a unique identifier in its cookies. Any redirects to that tracker during the 24 hour window will be able to associate tracking data with that same identifying cookie. However, once ETP 2.0’s cookie clearing runs, the identifying cookies will be deleted from Firefox and you’ll look like a fresh user the next time you visit the tracker."
It's not clear to me if this only affects "redirects" as they call or it will scan for all known tracking cookies and eliminate them. I'm also unsure if the data layer acts as a redirect.
