Nice Extension For Viewing Hd video and Low Mode always select you want select.

Messes up theater mode making videos too tall for the window.

Was a good addon to block suggested video auto play while keep main video autoplay "ON" to not push extra buttons. Now it doesn't block suggested video from autoplaying anymore. Now you got to totally turn off autoplay and play every single video you open manually or deal with stupid suggested video comming your way all the time.

Ok

It has only one issue: when playing the next video in a playlist for some reason causes the window to scroll down which leaves the top of the video hidden. This is not a minor issue and that's very unfortunate because this extension would be perfect otherwise.

Workaround by commenting the scrollTo function in ythd.js and disabling auto-update.
