This is why I only use old.reddit.com. If they ever stop providing the old Reddit, I doubt I'll keep using it. Sure the old one isn't perfect, but I find the new one borderline unusable, even on a modern laptop.
There's a furniture chain here that has a website so terrible, I just gave up on trying to buy what I wanted from them. So much happening in JavaScript to make things happen on the page. I have to imagine it's also terribly written, since it freezes up the tab most of the time, and Firefox suggests killing the script.
