How to add a site to 'allowed' list? Why I cannot do it by click on plugin icon in toolbar?

Does exactly what it is supposed to do. Knowing then what I know now, I would have never signed up for facebook.

It works well. I also recommend Firefox Multi-Account Container Addon by Mozilla.

you should be able to add a new site to the allow list

Excelente, recomendada 👍

Getting a link on the allow list is very very very difficult!!!

Great protection of Facebook's horrible privacy-breaches. It gives subtle warnings about where and how Facebook is tracking you and contains (most of) it, without getting in the way of your browsing experience.

I'm using this one together with Multi-Account Containers. It just installed another container on top of Multi-Account Containers and is letting me know how much it is protecting me from Facebook.
