Very useful, lets you do some basic things YT should just let you do.

good ex

Addon is broken again. You have to double stretch to get cinema mode to work.

A must need for Youtube. I personally use setting default resolution and making sure the comments are sorted by new

Saves so much time in the long run

As they succumbed to Google's ressure to stop blocking ads, makes this kinda pointless. go elsewhere for that.

the automatic video stretching function to full screen stopped working, also the top panel with search became separate, when opening each video you have to go to the extension settings again and click the checkbox, and then scroll so that the video is fully visible and the top panel is not visible
ps fix this please and i'll return all of the 5 stars)

Causes music audio on some YouTube videos to become mute.

Was working really well for a long time, but recently it has been extremely buggy and causes YouTube to lag. Videos tend to stutter, the expand video player option doesn't work, the play speed is useless (because of stutter), and in general a lot of the features are currently broken or cause more issues than its worth. I love the extension, but I'm going to disable or uninstall for a while and wait for it to be fixed.
