Just did a quick update to the add on, mainly to be able to quickly enable it and disable it, just clicking an icon in the URL bar.

Also open sourced it

Is there a scriptlet that could be run to do this in an Android browser like Hermit?
I don’t know how to do that.
I’ll be using Firefox nightly to be able to install it.
