usless I can`t write when I watch the video

Malware , this extension damage to browser and impair translator !

its a nice extension but not perfect, the pop-up window has a big title bar and it doesnt float on top of other windows, which makes it useless

Take you to a page trying to convince you to install after you install??? (Why)
Also, it doesn't float

Useless, I was looking for an alternative to videonail that actually works.

Amazing! Essential for the new Firefox Quantum in order to maximize video screen size to it's fullest potential, only thing left on screen after is title bar! Great job developer, looking forward to seeing that title bar disappear in the future tho!
