Very good point.
Yes unfortunately tightening browser security too much can break many sites.
I should point out I have not set my browser that tight, but found the page useful for explaining the use of certain features.
I don't require that level of anonymity, and am more interested in malware protection.
However as this forum is "Private Browsing" I thought others may like the anonymity options.
Hopefully this thread will turn into a more normalised list of options useful for a wider audience 😎
