One of the essentials for privacy and anonymity on the web which cuts off facebook tracking from outside of facebook. I combine this with google container and twitter/x container. In addition you can use about:config privacy.firstparty.isolate = "true" or privacy.partition.network_state = "true" to isolate webpages from eachother.

If the container is accidentally deleted it can glitch out and does not re-create it by itself, requiring you to manually re-create a container to fix it. Otherwise this works great!

Quite useful to keep the cookies isolated

Really love this add-on. I appreciate anything keeping Facebook disconnected from myself.

As I don't know how else to potentially report a bug or anything like that, I'm also using this review to inform that there appears to be an issue with Etsy. When attempting to log into Etsy (with email login) it says there is an error until I try with Etsy allowed in Facebook Container. I'm not sure if this is something fixable or if Facebook has found a way to break Facebook Container.

I don't even really know if it works but I find it really cool that firefox themselves made this extension because fuck Facebook and all other large and megacap companies led by psychopaths.

This extension WILL completely break Threads website. I'm assuming it blocks access to some necessary Instagram stuff.

Never downloaded the Extension. But I've always been perplexed why so many people issue 1 or two stars and NO review. Just sayin
