I don't see anything in that thread about consent banners, only that privacy badger tries to identify trackers not on its blocklist, a feature I don't want. I also don't understand why blocking consent to receive cookies is at all useful when you can simply block the cookie after consent.
On the off chance you're talking about blocking cookie consent banners (i.e. the popups on websites that ask your consent to send certain cookies), uBlock does that.
I'm sure your PiHole and USG almost fully cover any downsides to your below average choice in browser extension.
something works well ≠ whole thing good
Turn on "Easylist Cookies" in uBlock. Also, I feel like a broken record, but why wouldn't you just use an extension like this?
Also, if uBlock's list is missing a cookie banner, it takes two clicks to remove it permanently with the element zapper.
There is no evidence in front my eyes?
