I tried this for a day or two. It broke a website (Twitch, I think it was) and I tried to find the "disable for this website" option, but there was none! In which case, I knew that any time this extension breaks a website I'd have to go all the way to the addons page to disable it (since there's no way to right-click and disable an extension). But why should I have to disable the whole extension for one page, and then have to remember to turn it on later when I visit another page? Just let me disable it for that domain.

Also, yes, the little ninja that appears is a bit annoying. If there are no cookie banners, I know that the extension is working. I don't need an extra element added to the page so I know the extension is providing value.

I've decided to go back to "I don't care about cookies". Even though it auto-accepts-all cookies, that's ok because I have privacy badger AND ublock origin preventing tracking from taking place. So there's no need for an extension like Cookie Ninja to do complicated opt-out functions on every page. I'm already protected by my other extensions.

Maybe with some more improvements and less of a superior attitude of how this extension is better than other similar extensions, team Ninja Cookie will have a decent extension for us.
