Define marketing cookie for me - do you mean 3rd party?

(Some possible control via Tools|Preferences|Exceptions... button allows you to customise by website, although I've never used it. Or just disallow all, which is what I do)

Edit: answer the question please, there may be an easy solution to what you want.

Edit2: No reply because god forbid there's an actual way you could take control, that would simply ruin everything (in a parallel universe, man complains the streets are rife with face stabbing but when presented with proof they're not, stabs self in face to prove otherwise).

Biggest problem with learned helplessness is that they like it that way. Gives them something to be angrily resentful about.

Easy, enable only cookies for the things you want (maintain your session with 1st website, plus core functionality like payments). Everything else are marketing cookies.

I used umatrix for years but gave up. The guessing what to enable to get a site to work got tiresome, and IIRC there was also problem with browser support.

Définition of cookies I don't consent to: any cookie that is not mandatory for the site to technically work.

You don't answer my question, then use a vague term of 'technically work' to ensure I can't give you useful info tl;dr you don't want to be helped.

[Rygian]

I'm sorry that the correct answer to your question is vague. Such is the nature of the Internet. Not my choice, not my fault.

[zasdffaa]

If you don't specify I can't help. If marketing = 3rd party then you can block these using the hosts file at the domain level, which I do. This blocks >95% of crap cookies. A clear question gets a clear answer.

[Rygian]

Marketing cookies can be same-site or third-party.

The only entity that can specify whether a cookie is marketing-related or not is the website. No one else can.

[zasdffaa]

You're right of course but 3rd party seem to be the great majority, so blocking them is a big easy win. Also, only 3rd party cookies can track between domains/sites, so that stops that, or so I believe.
