No Stupid Questions

The annoyances filters in uBlock Origin take care of these, I believe there are a few filters specifically for this exact issue, named appropriately.

Friendly reminder that consent popups that don't have a clear "reject" option right next to the "accept" button are a violation of GDPR. You can report these to your country's data/privacy governmental body - for example Datatilsynet in Norway/Denmark, CNIL in France. You don't have to do it for every website that you go to, obviously, but if you do it even once you're helping solve this problem for more users than just yourself.

Others have given you some good technical solutions - personally I use the uBlock Origin + annoyance filters enabled approach, and use Firefox on Android to get the same experience there.

Consent-o-matic on laptop. Usually I'll go through the options and be annoyed. Sometimes I can't be bothered and hit accept all.

You can install uBlock Origin, the imho best ad blocker under the sun, and activate both the “EasyList Annoyances Cookie Notices” and the “AdGuard Annoyances Cookie Notices” lists. https://ublockorigin.com uBlock is available for all the most common platforms Chrome, Firefox, Edge, Opera, and there’s a manual install, too.

Consent-o-matic seems to work about 80% of the time. I run the Firefox plugin at home and the Safari extension on my phone.

noScript with blocking all Scripts by default. Most sites rely on javascript to ask you the cookie question. Of course that will disable all other javascript functionality which i have to enable manually if I need it.

I don’t care about cookies extension or ublock origin with Fanboy's Cookie List + Cookie autodelete extension

I've been dabbling with duckduckgo recently. there's a function in the browser settings to allow only what's necessary for the site.

There is an HTTP Header, called "Do Not Track", but unfortunately, it has been broken.
The idea was that even under legislations that allow assuming users want to be tracked, this header being set by explicit user action would have been clear evidence that this assumption is wrong in this case.

Unfortunately, Google and Facebook refused to comply outright and with their tracking software running on pretty much all webpages, compliance was never an option for all those webpages.

And Microsoft killed it off completely, by setting it per default in Internet Explorer. Might sound like a good thing, but it meant that the header could be there, even if that particular user actually fucking loves being tracked, which meant it was pretty much legally void.

If I have to click: 'deny' a gazillion times, then I just leave. If they have the alternative: 'deny all', then it's OK.

I don't care about cookies

The dialogues are not primarily about cookie consent but consent handling personal data. With that in mind, my primary concern is not giving that consent unnecessarily. I'm not interested in any personalized tracking when they could do enough usage statistic without consent and without sharing personal data with other parties. (That's why I won't use browser extensions that simply accept everything with the primary purpose of the consent dialogs not showing up.)

Consent-O-Matic is a browser extension that will decline any consent as far as possible.

It doesn't work on every website but that's better than auto-accepting - because I don't want to give consent.

Sometimes, when the barrier is not too high, I use decline all or open choices and save (verifying defaults are off). Depends on what it is though; often times it's not worth it to me to invest just to read their content. (Especially when it's regurgitated from other sources.)

If I can't use a website without consenting to personalized tracking I leave.

Another alternative is using alternate frontends to websites/services or the web archive.

My general view is that any service they could want to provide would be able to be served without consent requests. Ads can be served without personalized tracking (and can still be contextual to content). Visitor and usage tracking/stats can be done in a way without sharing that information to third parties and without individual user tracking. Legitimate interest and handling data to service (according to terms/contract) do not need consent. So really, there is no need for any consent.

/edit: I will be trying out ublock origin's hiding and reading up on Firefox automatic rejection mentioned in other comments. I expect them to behave better than the Consent-O-Matic delay of it going through all settings.

I installed Hush (for Apple devices). Totally even forgot about cookie prompts
