Mozilla also complained about GooTube
Chris Peterson @cpeterso
YouTube page load is 5x slower in Firefox and Edge than in Chrome because YouTube's Polymer redesign relies on the deprecated Shadow DOM v0 API only implemented in Chrome. You can restore YouTube's faster pre-Polymer design with this Firefox extension:
And it did fix the problem on 52 ESR and happily got rid of the huge white space found in the current design as well. I'm not sure if the latest version of Firefox (or in my case Waterfox) has worked around this, as I've still got the extension installed and will keep it installed just so I can see a less cruddy design.
