Can the Fix Major and Fix Minor site issues settings actually work, please?

In the Firefox settings (Settings > Privacy & Security > Advanced settings (under "Enhanced Tracking Protection" > Customise tracking protection) are two settings:

Fix major site issues (recommended)
Fix minor site issues

Despite me having both enabled, embedded YouTube videos are broken on the vast-majority of sites I go on, and it says "Video player configuration error, Error 153. Watch video on YouTube"

What is the point of these settings if they don't actually work?

Surely the whole point of them is to enable whichever third-party cookies or trackers are required for that content not to be broken.

(And yes, before anyone asks: I've tried opening the sites in a Private window, where my uBO extension is then not running and this is a Firefox Tracking Protection issues. In Microsoft Edge, all the same sites work with their tracker blocking enabled, and uBO Lite on the fullest mode.)
