List of websites that break with Firefox hardening?

Does anyone know of good lists of websites that break when used with hardened firefox like LibreWolf/Arkenfox and what settings to change to fix them? I found this list by Phoenix, but it seems incomplete

  1. Twitter is broken with my personal configuration (Firefox configured via Arkenfox & uBO in medium mode). I could fix it (by whitelisting a few things, but I prefer to leave it broken, twitter is a cesspool, and I appreciate have a little extra friction/annoyance to discourage myself from using it)

If you’re in the job search, expect most video interviewing websites (i.e. hirevue) to break. Some of them won’t work with non-hardened firefox regardless

My current biggest problem is ClownFlare and the spyware that they serve every once in a while from their “challenges.cloudflare.com” domain. Many websites choose to be proxied behind them, so I do not have much of a choice when browsing the internet. My browser usually blocks their fingerprinting scripts for being potentially malicious, but that often causes websites to no longer function. I am sometimes forced to go scanning for domain IP history, so I can modify my DNS settings and have the domain point directly to the real website IP address to bypass the CF proxy. It sometimes works. I’ve already complained to a number of website admins, but I’m mostly met with deaf ears.
