Firefox and Chrome/Chromium use software video decoding by default. They might also have "hardware acceleration" options for you to try, but to the best of my knowledge they don't do properly efficient hardware decoding. So this is a bug (two bugs) in the web browsers.

For a proper future solution see:

For a simple workaround that works today, see:

Another issue you will find is that Gnome Shell (especially Wayland sessions) stutters and drops frames more than it should. And this problem will be visible in your videos too. I have a list of causes for that:

Many people report better performance using Xorg sessions, for now.
