I am glad to see the cookie law, as misguided as it was, be enforced. Online advertising is an oligopoly with a stronghold on network effects.
However, I wish the law were solely about sites working with cookies disabled. The prompt on every website is driving me crazy, to the point of installing extensions like https://www.i-dont-care-about-cookies.eu/ (though this has been acquired by Avast apparently, so I won't ever update from 3.3.2).
Ever since the first browsers, cookie preferences were customizable in them. Websites should not duplicate that functionality, but merely respect it.
You could try https://github.com/OhMyGuus/I-Still-Dont-Care-About-Cookies if you don't trust avast.
