owned by avast

1) Causes problems on websites and breaks them. betterworldbooks.com The issue isn't that it causes this but that it requires you to dig through every extension to guess what's breaking your websites.
2) just found out the extension was acquired to potentially farm data?

This extension has been acquired by Avast (which itself has been acquired by Gen Digital Inc., a large tech conglomerate) and I simply don't trust Avast with my data.

Sold. Use I still don't care about cookies.

it works, but i would really like a privacy policy

Use I still don't care about cookies instead

Don't bother with this and instead install "I still don't care about cookies"- a community driven and open-source version of this add-on which nowadays probably gathers your data.

Has been taken over/sold out to some company who only uses it to steal data and doesn't even maintain the software.
Because of a Firefox bug it's still being shown as recommended and checked by Mozilla in your add-on library, even though they removed that flag some time ago.

As other mentioned used to be FOS but now is in hands of a company that has had controversies surrounding privacy

Non è più buona come un tempo. Si scorda spesso di levare la barra dei cookies

Une autre extension de merde qui n'est plus capable de faire son travail
