Really a very useful extension. I’ve been looking for this for some time. Great job!
Sugestions:
- Resizable window (drag a corner)
- Adjust opacity of the video window?
- Show youtube settings button
- It’s not working with youtube playlists.
- The current resize window function does not save the settings when closing Firefox.
- Run with all videos and not only on youtube.
The return to flip button should continue the video on the same flip (do not open a new tab) and continue playing the video (do not re-start the video).
