Seria possível criar uma extensão semelhante para a rede social Twitter?

Doesn't appear to do anything for me (FF68.0.2, Wind10 Pro64). No blue tab for FB pages, icon on taskbar greyed-out...

There are certain sites I would like to be able to whitelist, but it appears the only way to do it is to disable it entirely. As others have said, there are places where I'm willing to allow facebook to know I'm there, it should be easy for me to add pages to the container/whitelist them.

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.
