Return Youtube UI by 42null
An extension that returns the look of YouTube to before everything became rounded. Preferences are available on the popup. Feel free to fork it from GitHub. I will try to update it as YouTube changes their site. Submit issues in GitHub so I'm aware.

About this extension
This extension uses JavaScript to inject JavaScript, CSS, and HTML into YouTube pages in order to replicate the look of YouTube before a more rounded UI was implemented. Updates are still being made, but much of the old look is already back. Changes are made to the look only, no data is ever sent or shared. To remove all changes made by the extension, just remove the extension and reload the page.
