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.

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

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

It works ⭐️

It works! Channels DVR doesn't fill the browser window but I don't want fullscreen mode. This plugin fills the browser window with wonderful full-size video. Thanks!

Mit diesem Plugin kann man Videos in Fullscreen in mehreren Tabs laufen lassen ohne das diese beim raustabben den Fullscreen-Modus beenden.

Often used this feature in Cent browser for a long time looking for it in Firefox. Thank you very much.

Very useful and resolved my big pain on macOS, the video player's default fullscreen always results to a system new full space, which is very annoying and hard to control/switch other app/tabs.

Thank you for the add-on. This browser tab/window-level full screen is what I wanted and searched for a long time.

Excellent work. If possible please add also hiding the tabs and address bar.
