A report published earlier this week claimed that YouTube’s new design performed poorly in non-Google web browsers and the issue was brought to light by Chris Peterson, Technical Program Manager at Mozilla who detailed the claim on Twitter.

“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,” Peterson explained.

“YouTube serves a Shadow DOM polyfill to Firefox and Edge that is, unsurprisingly, slower than Chrome’s native implementation. On my laptop, initial page load takes 5 seconds with the polyfill vs 1 without. Subsequent page navigation perf is comparable,” he added.

To fix this issue, you would need to return to the old YouTube interface and disable this alleged throttling bug. It is quite a challenge to find a way to disable the new YouTube UI and return to the old interface to address the performance issues in Microsoft Edge.

• Navigate to the Application tab and double-click Cookies to modify it.

• This will expand the category and you would need to select the option containing

• In the right pane, Double-click PREF to modify its value and paste the following

• al=en&f5=30030&f6=8

• Close the Developer mode and refresh the page.

• Edge browser will load the old YouTube and the performance issues will be

Google Chrome is currently the number one desktop browser with a market share of around 60 percent and Microsoft Edge has close to 4 percent market share.
