Youtube page load is 5x slower in Edge and Firefox than in Chrome

YouTube’s newly designed Polymer framework brings many improvements to the video sharing platform, and it also brings new controversy in the browser field. Mozilla’s technical director, Chris Peterson, posted a tweet to slam Google, saying that the technology that the Polymer framework relies on is only available on Google Chrome and slows down on Firefox and Edge.

Peterson said: “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.”
