Invidioucious by JanKKM

All of Youtube but without the privacy issues that come with Google. Invidioucious catches every request to Youtube and redirects to an Invidious instance of your choice (default is invidio.us), zero connections to Google if you enable proxy mode. You can preset the options that Invidious offers:

-Dark mode
-Thin mode
-Video quality (small, medium, 720p or DASH)
-Proxy mode (if enabled no connection to youtube/google are made)
-Autoplay
-Loop
-Any other argument that invidious supports
-You can also set the url of the Invidious instance you want to use.

The settings are persistent so you can clear cookies in Firefox without loosing them.

It also works on embedded videos.
