Is there any good method that forces my web browser to play all YouTube videos on the lowest definition, even if the video offers a higher resolution?


Log in to YouTube, go to the playback settings and select that you have a Slow Connection.

  • This will use a lower resolution, but often not the lowest. e.g. 360p vs 240 or 144. – jim Oct 1 '15 at 6:54

Add &hd=0 to the YouTube URL. That will display the video in 360p.

Ex. http://www.youtube.com/watch?v=nxdtVWvfFSU&hd=0

Additionally, you can add &hd=1 instead of &hd=0 to the URL to get 720p (if available).

E.g.: http://www.youtube.com/watch?v=nxdtVWvfFSU&hd=1


By adding the parameter fmt to the URL. See http://en.wikipedia.org/wiki/YouTube . Google can help you find Greasemonkey scripts that do that automatically.
