Last year I was building a "Cookie Consent" banner for one of my sites. I wanted to be transparent as possible with it so I had this box come up in the corner to ask for permission, big blue button for OK, big red button (of the same size) to decline, zero dark patterns.
Looking at the analytics after the fact made me realize why these cookie consent boxes use so many dark patterns. My acceptance rate for the box was like 4%, I tossed out cookies (and the banner) in the next update.
I never click on cookie consent banners, period. It has nothing to do with me not noticing them. I just leave them where they are unless they are too intrusive. If they're too intrusive, I leave the page.
The reason that I don't click on them is because I've had bad experiences clicking on them in the past.
I still don't see those sliders. Is it something you have to enable in the preferences? Is it mobile-only or something (I don't use a browser on my phone at all, so I wouldn't know...)
I see them now with Firefox on desktop, didn't enable anything specific. They definitely weren't there when I last used the blocking feature, which was probably some time last year.
I've been using an old version of Waterfox until recently, when I finally had to change to a modern browser. Looking at the alternatives, I chose Firefox as the least bad of the available options. On the plus side, this means that uBlock/uMatrix is an option for me now.
The best cookie banners have a small neutral button labeled OK to accept only required cookies and then, on the right, a happy big blue button to Accept All. Transparency!
