Ever since Google has released the new re-designed YouTube, many users reported that it loads quite slow on Firefox and Microsoft Edge browser. Though it might look as Google is throttling the YouTube browsing experience on two of it’s biggest competitor browsers; the issue is more technical than functional.
Confirming this report on his Twitter handle, Firefox engineering team program manager Chris Peterson wrote ”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”
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: https://t.co/F5uEn3iMLR

Along with acknowledging the issue, he also suggested, a temporary fix to get around this problem by restoring YouTube’s faster pre-polymer design using “YouTube Classic” Firefox extension.
Just click Add to Firefox. When you load YouTube, it should be noticeably faster.
For Safari users the process is a little more tedious. You can bring back the old YouTube design back by using the Tampermonkey Safari extension.
Once you download theTampermonkey extension:
- Click the Downloads button to expand the menu.
- The Extensions preferences pane and prompt will appear asking if you want to trust the extension. Click on Trust, and you’re ready to go.
The next time you visit YouTube, it may take a little longer to load the script for the first time. But once the script runs and the design reverts to the old YouTube layout, you should notice a significant increase in page load time.
