Yeah, i use something similar. For steemit at least, that looks like the extent of the tracking here (which is great). Though, oddly enough, steemit doesn't seem to be looking at your facebook data from your browser. It looks like steemit saves the name and email of the facebook account you signed up with. Im not sure who this information is or potentially could be shared with, but yes, they definitely collect and store it.

I used a sock-puppet facebook account to sign up for steemit, for privacy reasons, and the name and email from that account still seem to appear in pages served to me, even though im logged into my real FB account while browsing.
