Works nicely! I wish there was an option to select the correct video in case there are multiple videos on the site. Maybe adding to the right click menu of the videos would be possible?

it just works.

Works fine on YT. Was really hoping to use it on a site that has Anime and Kiss in the URL. Does not detect the video on that site :(

Does what it says on the tin. So far I have tested it on a Twitter livestream, YouTube, and ESPN+. YouTube and ESPN+ worked flawlessly, but Twitter was a little buggy; activating the plugin caused the video to pause, and the top and bottom of the video get cut off (instead of having black bars on the sides).

Annoyingly, it replaces the website's video player with Firefox's generic player, which is sometimes inferior. However, sites with good video players usually also have good theatre modes, so this add-on generally isn't necessary on those sites anyway.

I am always weary of installing relatively obscure extensions because of security concerns with trusting unknown developers. However, I have reviewed the entire source code of this addon and have found nothing suspicious, so I feel safe in recommending it.

I was looking for this solution, from thinking of buying portable monitor til I've re-check the firefox plugin. Works like a charm... hbo go as some issue with windowed full screen, youtube and netflix also eat bit chunk of real estate when u not enable full screen. this is definitely good solution

when it works, it works really good.
read as, sometimes it fails, but sends video full-window really nicely when it works.

Tested it on embedded videos in newspapers - killed the embedded video completely.

Отлично работает в IceDragon на Twitch, кликаете по иконке дополнения, включается и также выключается, видео растягивается по размеру окна, то что надо.

It works ⭐️
