If you are wondering why YouTube is loading so slowly on Microsoft Edge, Safari, or Firefox compared to Google’s Chrome Browser. Here is the answer for you As Google redesigned the YouTube experience last year, but the site still uses an older shadow API that is only used in Chrome, which makes other browsers render YouTube much slower. Chris Peterson, the technical program manager at Mozilla (who oversees the Firefox browser), finally gave a detailed analysis and confirmation of what we all have experienced: YouTube is slower on Firefox and Edge.
Chris Peterson explained:
“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,”
