Blocklist Facebook domains
I highly recommend using uMatrix[1][2] if you're very privacy-conscious.  It's the full-blown everything-at-your-fingertips console.By default, it blocks third-party scripts/cookies/XHRs/frames (with an additional explicit blacklist).  You then manually whitelist on a matrix which types of requests from which domains you want to allow.  Your preferences are saved.It is a bit annoying the first time you visit any new domain, because you need to go through a bootstrapping whitelist process to make it work.  After a while I find I do it almost automatically though.I use it in conjunction with uBlock Origin and Disconnect, and it still catches the vast majority of things.  As a nice side-effect, I find I keep pretty up-to-date with new SAAS companies coming out!---[1] https://chrome.google.com/webstore/detail/umatrix/ogfcmafjal...[2] https://addons.mozilla.org/en-US/firefox/addon/umatrix/
