First of all, great extension. I will definitely give 5 stars, there are just a few bugs I'm experiencing at the moment which makes it really hard to use it. A fix would be awesome, thanks for your hard work! Im using an Android phone btw.
1 Youtube. When I'm on YouTube's main page, the extension works like expected. Once I watch a video, it doesn't change the browser to fullscreen, but the video player itself. It appears like clicking the standard full screen icon from YouTube's Video Player just in a buggy way because some buttons in the top right are overlapping each other and the button to revert the videoplayer's full screen doesn't work. So every single time I have to slide up so that my navigation bar appears to click the 'back' icon which deactivates the full screen. Would be great if you could implement that the function just convert the browser into full screen, not the video player.
2 Control Button. The control button of your extension which activates full screen mode has one little bug. When I click it, the information passes through it, so if the control button is located above a video or link, the video starts to play, or a new tab opens. Would be great if the browser ignores touchscreen interaction at the button's location.

I have the newest version, driver and everything. Thanks in advance, love this extension :)

First experience confusing as the pulltab doesn't appear on addons.vaultpit.io, only on other sites!
After that it works very naturally.
I'm still puzzled as to why this functionnality is missing in stock Firefox Android...

It works! The only thing I would also like to have is to be able to change the position of the toogle button. Thank you!

Solid work, I appreciate the necessary addition to Firefox, I just have one request. Can we please have the option to make the pull tab dissappear after a few seconds, it's so prominent, especially with the chosen colour scheme, kinda defeats the purpose of 'fullscreen'. Please and thank you.
