uBlock Origin has been useful when it comes to protecting my family computer. There are so many hostile ads and websites out there. I highly recommend it (or Pi-hole or some other good filtering tool).
Personally, I have a lot of trouble with websites breaking because some script was rejected. I think its a big ask to say "if you think this website isn't working correctly, make sure the "*.cloudfront.com" is allowed to load JS resources.
