Here’s how to load up youtube 5 times faster in safari
It’s not Safari’s fault if YouTube works so badly. In fact, the same problem also affects users of Firefox and Microsoft Edge. All because of the way YouTube is designed.
Google builds its services to work better in Chrome. Some have been prevented from running inside rival navigators at all. What’s slowing down YouTube is that it’s still relying on a deprecated hidden API that only Chrome still supports.
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

This makes YouTube five times slower in Safari, Firefox and Edge, according to Chris Peterson, a program manager for Mozilla – but there is a way to change that.
Speed up YouTube in Safari
You can ask Google to switch to Polymer 2.0 or even 3.0 APIs, which are supported by other browsers. This would load YouTube pages much faster. But that will probably not work.
The simplest solution is to force YouTube to return to an older model that does not rely on the Polymer 1.0 API. You will lose its dark mode function and a slightly more polite look, but the experience remains the same.
Here’s what you need to do if you use Safari:
- Download the Tapermonkey script
- Tell Safari that you “trust” the script when it requests your approval
- Download this user script that forces YouTube to use the classic mode
If you use Firefox on your Mac, Mozilla has worked hard for you. Just download this Firefox extension that automatically forces YouTube to load its old design.
