I love the idea of this, but recently (2/2020) it hasn't been working. Facebook still loads in the container, with a white bar underneath. But it is definitely still seeing my search history in other containers. I'm getting ads about quitting smoking.
I have never smoked. But yesterday I did a lot of research on rehabilitation from drug misuse for a character in my novel. This is the only time I can think of that I even approached the topic of drugs or addiction on my computer. But facebook knows, despite being in a container. :(

Needs a whitelist feature

good!

With this plugin enabled
1. Do a google search about XYZ
2. Login to facebook
3. You will see facebook ads about XYZ!!!!!!!

Great idea, unfortunately UNCLEAR how to add exception

Can't honestly say how well facebook container works but i think i get fewer suggested pages, ads, etc (though I have a number of anti-ad solutions in place, aside from FB container).

I've only given the extension 3 stars though because it was listed as available on FF android and installed fine too, before the recent update to 68.2.0.

Now i find the "about this extension" detail says it doesn't work on FF android. Yet it did and was available from the app add-on list. Didn't seem to cause any issues either on FF android.

I am glad to have this protection but when I decide to share something I don't want it to tell me that I can't because it was blocked. The option to override it out to be be readily available at that specific moment in time. Who has time to logon in order to explore how to add a site? That's a very big negative in my mind.
