Oh no, anyway.

It just stopped working one day.

Just found out that Avast purchased this Add-on. I value my privacy, and that's reason enough for me to delete this Add-on, and switch to the open-source "Community" version (fork), now called "I Still Don't Care About Cookies".

Can't recommend it anymore since it has been bought by avast, definitely not a good company.

This extension has been bought by Avast. Kudos to the developer but Avast is the worst AV, technically and regarding privacy. Fly, you fools!

I can no longer recommend this extension. "I still don't care about cookies" is the way to go.

Fuyez ! Extension appartenant maintenant à Avast bien connu pour ne pas respecter la vie privée des utilisateurs
FUYEZ !!

Blocks the cookie messages but allows far too many cookies to be enabled on my browser, so I end up with thousands of websites tracking me without realising it. It basically just seems to say yes to everything without asking me.

Would be better if it rejected more cookies instead of just invisibly accepting so many cookies.

Owned by Avast!

Avoiding since it was bought by Avast

It was great until it was bought by avast...

I would never use anything offered by Avast. Warning: Do not use this extension if you want to keep you information private!
