This addon works well on Chrome, but switching back to Firefox, it's finicky.

On Youtube, the addon only kicks in after going fullscreen and leaving fullscreen once.

On Twitch, the behavior is similar, but when clicked the third time does not pop up the menu, but goes into Twitch's "Theatre Mode" and opens the menu at the same time. On Chrome, the window goes into "Theatre Mode" and then pops up the menu on the first click.

I don't know if this is because the Firefox version is missing the "PiP" option?

maximize size is greyed out on windowed floating mode

Been using this for years. Accept nothing less!

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.
