Have you managed to verify this or you're just assuming it ? I'm just assuming it, that's why I'm asking. Like have you made a request for your data from Facebook / data brokers and it looks straight ? I trust Mozilla to the fullest and have made no effort to investigate.

You can verify it for yourself. Facebook lets you view this information. https://www.facebook.com/off_facebook_activity

Facebook collected this data for years but only recently started disclosing it. There's no reason to trust that they're disclosing all the data they're collecting.

I don't trust that this is all they have about me. Wasn't there reports that they were generating dark profiles about people not even on Facebook (by mining contact information from others)?

That skepticism is definitely healthy, but by the GDPR, this is required to be every single thing they have on you, under penalty of significant fines.

That doesn't mean it is everything... but it at least makes that a little more likely? Some light optimism for you, I guess.

Edit: seems even this isn't necessarily true.. damn.

They have to tell you everything they know about you, by law... but that doesn’t mean this webpage contains every information they collected. And getting everything is rather complicated: https://ruben.verborgh.org/facebook/

Only for EU citizens.

Thank you very much for that link. I didn’t know about it.

lol

I guess I though it would be something like https://www.facebook.com/shadow_profile_activity

Interesting...I've been using the Facebook container for well over a year and have been very careful to only access facebook from it....but they still list very recent (like yesterday) data in my off_facebook_activity. This is very frustrating.

Use umatrix to block all trackers. You are probably getting caught by third party trackers

You can check this in the settings. They really obfuscate and have dark patterns here but last time I checked it was there.
