I run benchmark regularly concerning privacy exposure, and I ran one this summer to find out all 3rd parties for a sample of high traffic web sites.
I collected and sorted the results by [3rd party, 1st party] pairs: this allows to see at a glance the most ubiquitous 3rd parties out there, i.e. those which have the ability to build a profile of your browsing habits.[1]
Facebook (through `facebook.net`) was definitely at the top in the benchmark, when using EasyList, EasyPrivacy, Peter Lowe's.[2]
I personally doubt a majority of users care that there is a Facebook like widget on any page, except maybe for a handful of sites for those with a Facebook account. So disabling Facebook globally with exceptions where needed is a top advice to reduce privacy exposure.[3]
