Very good but not wow as "InstantView for YouTube" on chrome store...

nice "opera inspired" addon, but it NEEDS something like "always on top" (I know WE limitations), but without that its practically unusable...

It needs "always on top" feature.

Need to play on top of windows feature !

Add On is great, really helps get full video window after the release of Firefox Quantum, from all the incompatible legacy add ons! Improvements need, remove title description on popup window, fix remove icon on playing on other youtube videos and it would be great.
