Redirects youtube to invidious
This is an extremely simple script (a single line of code), which redirects you from a youtube video page to the corresponding page on yt.cdaut.de (which is an Invidious instance).
It also works for embedded videos, allowing you to watch the embedded youtube video using Invidious's embedded player rather than the youtube one.
See the Wikipedia article for some insight.
Just a note that, most Indivious instances by default still connect your device directly to google's servers to download the video, only falling back to proxying through their own servers if you either block googlevideo.com requests, or (this requires first-party cookies) use the Proxy videos option on the preferences page.
The script will still allow you to use youtube.com if you navigate to that site via its homepage or another page which doesn't look like youtube.com/watch[...].
So, to be clear, if you navigate to a video from another youtube.com page, you won't be redirected. If you then refresh the video page, you will be redirected at that point.
