It works great! Thanks!

After removing the addon any video doesn't get full screen.

works perfect so far

Perfect.

Works great on sites like youtube but for some reason the addon makes so that I cant login to my switch/moodle account.
An option to block the addon from accessing certain websites could resolve the problem for me.

Works great. Happy it is available on Firefox, as I just switched back from Chrome. Absolutely essential extension for me!

Usefull in some cases.
But, I would like a default mode in "fullscreen" without asking
( and, for some sites/domaines add a specific mod )
So, a "default option" should do five stars here.
Thanks for all

Sometimes work, sometimes not.
And can't reset the config for a specific page.

working perfect this extension allow me to show a web remote desktop like a floating box only the remote desktop...it is fantastic!!! thank you so much for this amazing work!!!! as sysadmin I love it

It didn't work

Finally found a way to window YouTube TV to watch split screen on an ultrawide. This is a huge improvement over a snapped window browser.

I have a collapsible tab bar, so enabling windowed full screen will fill up the entire program window, which I can then place wherever I wish. It's perfect, and wouldn't be possible without this add on.
