I think it would be a nice feature to have in the browser. Does anyone know if Chromium or any Chromium forks are already working on this? |

Is your feature request related to a problem? Please describe.
Apparently there is a new way to track users by tricking the browser into thinking the cookie stored is a 1st party cookie (https://nakedsecurity.sophos.com/2019/11/25/ad-blocking-companies-block-unblockable-tracker/). Firefox has an API to look up the real domain behind a CNAME. Are there any plans to introduce some native ability to do something similar in this project?
Describe the solution you'd like
Some way of exposing the real domain behind CNAME records.
Describe alternatives you've considered
