How to to automatically refuse GDPR consent requests?

How to to automatically refuse GDPR consent requests and only opt-in strictly necessary cookies (session cookies, etc...) ?

I tried the Never-Consent WebExtension on both Firefox and Chromium but it does not work on youtube, google, dailymotion, *.stackexchange.com, etc...

How can this be set from within the browser's settings on modern browsers?

Solution 1:

All the sites I have used (many) have all different approaches for selecting all cookies, including a few "all or nothing".

There is no commonality and accordingly no practical way to automate this.

We all just have to accept (or not) as we go.

I have not seen any major issue in cookies from reasonable sites.

You might look at the cookie view apps and delete old cookies. Nirsoft can do this, for example.
