Regarding the Ad Tech section, I found value in the August 6th episode of Security Now titled "How Revoking!" where he's talking about 3rd-party cookies handling in Firefox.
Generally speaking, I'm sure it's difficult to find a general balance between privacy and usability, and I tend to want a purist viewpoint on blocking all 3rd-party cookies if I set Enhanced Tracking Protection to Strict. The above episodes explains why it's not 100% doing what we expect, which was troubling to hear!
