SafariTube - Fix YouTube on Safari

What is this?

SafariTube is a simple userscript for Tampermonkey, which simply makes YouTube think it's running on Chrome, enabling a much better user experience, from features such as hover previews to improved video playback and an overall improved YouTube experience.

How do I use it?

1. Install Tampermonkey from the (Mac) App Store
2. Configure Tampermonkey to your liking (optional, but recommend checking general update settings in particular)
3. In Tampermonkey, go to Utilities and look for Import from URL, then specify the downloadURL or updateURL from the script below (they're the same), then click the Install button and continue with the script installation
4. Enjoy a better YouTube experience, as well as automatic updates to this script*!

*As long as I remember to update it, if and when it breaks!
