Since I have been using an active pen in Windows for 22 years, this extension looks like a Godsend!

Unfortunately I cannot seem to get it to do what it's supposed to do. Basically, while the mouse draws fine, the stylus, like the finger, scrolls the page while drawing, which conflicts. Might have to do with FF gestures settings.

Also, it seems that the required permission needs to be given once at a time, at least that's what the FF extension button displays.

Lastly, pinning the icon doesn't seem to serve a purpose; could it act as a toggle? ctrl-x is fine but you need a keyboard... The stylus is my keyboard. I mapped a mouse button to the shortcut.

In any case, I want to encourage the author with this fascinating project. Cheers.
