Does Exactly What it Says Rated 5 out of 5 stars

Does exactly what it says. Nothing more, nothing less. No frills, options, or additional features. It simply adds a button (shown above) that turns document body contentEditable on or off. If that's what you need (and all you need), here it is.

This review is for a previous version of the add-on (1.0.rev162.1-signed.1-signed).
