I don’t know why the downvotes. Sadly some webpages are made only thinking in chromium, thus working worse in other browsers.

I have found the same issue with youtube. I still use firefox, but youtube under firefox works worse than under chrome or other chromium based browsers. Probably it’s google fault this, I’m certain they do it on purpose.

Also clarify that I use an old computer that struggles a bit in general, so newer hardware may have not experience this, maybe?
