Yes, you'll have to whitelist your sites that you don't want to be signed out of, but otherwise, it works wonders! Even from just having used it for a few weeks, it's deleted some 19,000 cookies.

Does what it says and has been no trouble for all the months I've had it installed. Only one of a few add-ons I've ever kept more than a couple of weeks. The instructions were easy to follow even for a 'non-geek'.

It does exactly what it says and I like it. Cookie AtoDellete does all the worrying about cookies for me.
Enough said.

Stupidly annoying add on. I'm not wasting my time white listing the sites I use, and being signed out of my sites constantly drives me up the wall.

Very nice

Ainda em testes, mas se apresentar bons resultados, voltarei e darei 5 estrelas.

great, the best ever

One of the most useful extensions I have ever installed.

I started with auto-deletion turned OFF for the first few weeks. During that time, I white-listed all the sites that I regularly visit. Then I turned auto-deletion on.

I have it configured so that I get a listing of deleted cookies whenever I close a tab. It's amazing how many there are that have a domain that's completely different from that of the actual web site. I assume they are tracking cookies and such. Nice to have them disappeared.

When I use my browser's (Firefox Quantum) cookie management page, there are so few cookies listed, and there are no longer any left that I want to delete.

Fantastic job!

SUPER polecam

A very useful extension. Thank you.
