It was such a downer to see this add-on (former Youtube Plus) stop working when Youtube changed his layout that I even stopped watching my video there and went for an external app. Truly the kind of add-on you can’t live without it once you tried it. And I’ve tried everything else, nothing came close to it, and by far. I’m so glad it is back again. I don’t really understand the need to change the name to Iridium, but who care ? This is a must have !

Enables full video playback while the mouse is over the thumbnail of a specific video.

Shift key toggles audio on video thumbnail playback

Enable player pop-up
When enabled a button will be displayed over video thumbnails allowing videos to be played in a pop-up window.
When launched from a playing video it will resume from where it was playing as well as when closing the same pop-up window.
[NOT IMPLEMENTED YET] The pop-up window can be resized and it will memorize the new size, with the minimum and default value being 533px in width.

Blocks all videos from a channel on main pages, with the exception of Subscriptions and Channel pages.

Default video quality
Sets which quality the video player should play. If the quality does not exist it will select the one closest to it.

Allow annotations on videos
Controls whether or not annotations can be displayed on the video.

Allow ads only on videos of subscribed channels
Controls whether or not ads can be displayed only on videos from subscribed channels.
