Great addon that seems to do what it says. However, it's not available on Firefox mobile.

The WhatsApp Web website belongs to the Facebook corporation, but is currently not isolated by this addon. Will it be?

Facebook is stopping me from adding some links to groups now I think because of my privacy addons. Not being able to use Facebook login on other websites is expected behavior for this addon and not a bad thing.

Excellent for its advertised use, though it seems to make it impossible to log in to other websites or apps using facebook. Sacrificing a bit of convenience to keep a multi billion dollar advertising company from tracking me is worth it, though

I love this extension! As a cool side-effect I now work more efficiently because I keep opening the right container for the right goal, work, personal, Facebook... Only thing (on windows) is that the shortcut CTRL+. (period) is also an shortcut for one-password. But the container extension shortcut overrules this. Maybe I can change this in one-password. But I though it was worth mentioning.

It does what it says in the name. It's effectively like a virtual machine that only affects Facebook. It loads anything related to Facebook into the container, like comments and like buttons on external sites. Of course, it's not perfect, and Facebook *could* still track you in some ways, but that's why you should use this in combination with Tracking Protection, and other add-ons like Privacy Badger.

Only reason I'd recommend against this add-on is if you absolutely have to use Facebook login on some sites, as that likely won't work. I'd advise just switching to a password login if possible.
