Firefox Enhanced Tracking Protection "Fix major site issues" option

I was setting up Firefox on a laptop and looking at the recommendations ( Privacy Respecting Web Browsers for PC and Mac - Privacy Guides ) and noticed that while Strict Enhanced Tracking Protection is recommended, there is no mention of the “Fix major site issues (recommended)” and “Fix minor site issues” checkmarks that Firefox settings offer. Should I be leaving both of these on? I could not find any posts or discussions about these. (I assume I just looked in the wrong place)
