Earlier quoted context omitted.
You don't have to put up with that. Protect yourself. Install uBlock Origin and NoScript.
Or another option: uBlock Origin + uMatrix. Playing embedded videos will need such an amount of configuration that you'll really want to watch it before bothering. This could be a positive or a negative, depending on the person :)
Noscript as the first line of defense against 3rd party scripts, uBlock in advanced mode for fine-tuning what content goes through, and uMatrix for being the safety net as well as providing cookie control and spoofing/referrer masking, since Cookie Monster still cannot work with multi-process mode.
I really wish uMatrix and uBlock would just combine forces or that uBlock would at least match uMatrix's privacy protection.
