a temporary solution to revert to the old ui. the new ui was put into effect since april and is slowly rolling out to users.

• runs automatically no need to manually do anything after installation
• lightweight no loops in the code
• opens youtube on install to prevent issues
• uses cookie method instead of url
• works for everyone even if you haven't modified the pref cookie before
• firefox support

(if we get $20 donated ill add it to the chrome webstore like I did with firefox)

Download the latest release (make sure its the .zip file)

goto chrome://extensions

(make sure developer mode is enabled)

Drag the zip file to the extensions page

You're good to go!

If it still doesn't work I would recommend refreshing youtube on the homepage atleast once

Im working on a css version/perm fix so this wont be an issue

your youtube ui should be back to normal!

feel free to contribute or send a pull request

This extension allows you to modify the 'PREF' cookie, which is responsible for the theme settings, and open YouTube in a non-dynamic manner, making it possible for the extension to change the URL autonomously.
