Note "I don't care about cookies" and "I still don't care about cookies" will accept tracking if that's the easiest route to get rid of the popup, which is a significant difference to the extension in this topic.
Pair it with uBlock Origin and Firefox Enhanced Tracking protection and it doesn't matter.
I don't have a plugin for disabling the banners, but I accept them if that's the easiest thing because I can already see that uBlock Origin blocked all their trackers anyway.
I understand the shortcoming but to be fair, if a website owner wants to track you he can do it even without cookie. I appreciate the gdpr for many reasons but the cookie banner constant spam is not one of them, I believe people just want to get rid of it even if it means agreeing to everything.
