There is also this official extension. IIRC, this also makes sure that all the meta owned sites are not able to interact with other sites, but can work fine with each other. It also makes sure that any links leading to their sites also only open in the container, maybe also sanitized to remove the tracker from original link. The last part I am not sure, as I might be confusing it with a different extension. But if you are using any of the Meta sites, I would recommend it.
