Check your configs. It may also be a setting on the network you’re using. My workplace’s internet has some sort of filtering system in place that happens to also disable YT comments. Pretty lame, but it’s their network. I just use my phone on 5G if I want to read YT comments or watch “18+” videos (not porn - some videos on YT are actually blocked).
Not a Firefox/uBO problem.
