Usefull since the invention of cookies Rated 5 out of 5 stars

Don't I know it! This is the one and only add-on I've used to manage all of the cookie permissions.
It's simple, powerful and it is intuitive at all.
OK, currently it has some issues in FF 42/43. But I look forward to see a solution soon. Who's guilty? Not this add-on, definitely! It worked well for years. The browser guys changed something - kaputt... Nevertheless -> ILIKEIT
