Good luck trying to figure out that is the issue if you don't keep it in mind at all times. (No matter how obvious it seems - hindsight will never not be 20/20.)
Random coincidence... This is the second post this has popped up in today. Another frontpage post mentioned this in regard to getting blocked by Cloudflare. https://news.ycombinator.com/item?id=37049016
Yep! Sorry, didn't mean to imply it wouldn't work at all. I'll edit my post if HN still allows me to.
I'll note that apart from a handful of sites where it causes additional checks and occasional breakage (noted them in another comment below), I'm really happy with that setting. I leave it on by default and only have to break out a fingerprinted Firefox profile on rare occasion.
