ok, but still many sites where cookie popups are displayed, at least you can see in the dashboard that it does work on some sites and saves you some time and nerves

I think it was doing something? I probably forgot because once the cookie popups are reduced you stop thinking about them as much in the first place. BUT sadly there is currently a conflict with the duckduckgo search engine. So I am sadly going to have to disable this one for the time being. I'll update the review once it is solved and I have remembered again how much I hate cookie popups.

in principal its great - and when it works it is that good. but it often breaks sites, currently it prevents duckduckgo search from working if enables

Excellente extension. devrait être obligatoire.
Énorme défaut : elle ne fonctionne pas sous Android, ce qui serait indispensable, vue la taille des messages de cookies

Indeed, this extension has lots of potential.
But the very big downside is that it noticeably slows down Firefox. I use Windows, MacOs and Ubuntu on three different machines and this happens on each computer i use, no matter the configuration.
