It helps to prevent Facebook's tracking (doesn't stop, but helps stop), but it is missing a lot of Facebook URLs. It only has 3 of Facebook's URLs built in, but it is missing the URLs for threads, meta AI, whatsapp, all of the FB help and company pages, and their other projects. There is actually an issue and pull request open for this on their GitHub, but Mozilla seems to be ignoring it, and because of that, I have to take off major points, since they know about it, and someone is fixing it for them, but they still aren't doing anything about it, which is unfortunate.

I've tried several alternatives and this one is by far the best. Straightforward and does the job perfectly.

I LOVE IT!

This extension does not help for me at all I will have 2 tabs open one facebook and the other one shopping and when I go back to facebook I have ads all over it for what I was just shopping for.

Doesn't work, I can search something in firefox and on another browser altogether will start getting ads for that type of product on facebook

I really like having this app to protect me from facebook's sketchy business practices

You have to manually add 'threads.com' to the sites that are allowed, then Threads will work again.

trash!! messes with your cookies, breaks zen functionality (essentials). TRASH

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.
