Great extension to get this cool feature, I've seen no issues with it, yet.
It is very handy to work with, let say now in my case, I've to do an essay, for which I'm learning out of someone's youtube videos, I can keep up writing without losing focus out of the LO Writer.

great youtube popup video addon, works great, will be even better if it can remove the top white title border or make it to match my dark firefox theme.

Unfortunately doesn't work how i needed it to. the popout appears fine and comes up quickly when activated but it only stays on top of other tabs if i don't click or type anywhere! as soon as i have to click on something else it disappears which means i can't perform other tasks without the video going to the back. basically works exactly the same as if i were to open the video in a new window and will not stay on top of my other tabs while i am typing

to make it really good the poput player has to be on top of the regular firefox page or in general on the top of everything so that you could use it while watching some other content in the background

Works as expected, but i wonder, is there any way to hide the info, like showinfo=0 ?
Also, it could close the initial window.

LE: Thanks for update 3.0, great features ! I like that now it closes the tab and hides the address bar too.
Related to my initial question, is there any technical way to hide the video title? When "Hide Popout Controls" is enabled, when I hover the mouse over, the bottom controls are hidden but the top row, with video title, "Watch Later", "Share", "Info" still appears. Can it be hidden too ? :)

LE: As user 14403038 stated above, an always on top option would be great :)

Thanks anyway, great plugin !

Works as expected.

it's necessary to make the pop up always on the top

Makes a new windows that plays the video but doesn't stay on top like I wish it could. also the title bar at the top is sorta annoying too :/

Amazingly Integrated! Uses built-in YouTube features like auto-play and start times, but with a very subtle button that fits right in with YouTube's own.
My only con is it has the URL and Firefox menu on it, which can disturb the experience, but I'm not sure that can be changed.

Extremely useful, especially if your OS supports keeping the video window on top of others.

So far, so good. Does what it's supposed to do without any unnecessary extra fluff.

just what the doctor ordered. Perfect!

Pops out the video just fine. But what's the point of having it pop out when as soon as you click on another tab or window, it gets sent to the back? Pretty useless. Opera browser does this correctly right out of the box.

Works well. Thank you.

Não me serviu de nada. Apenas abre o video em outra janela, mas não fica sobre as outras. O que não tem motivo nenhum.

This add-on does exactly what it says on tin, pops out videos in a new Firefox window without all of the YouTube padding. Works well every time. Exactly what I needed.

Exactly what I wanted. Makes viewing while working more enjoyable.
