Still does not work with Firefox 26. Please update this to work, as it sounds very useful.

Does not work with Firefox 22 in Gnome-shell (Fedora); though, initially it does display a prompt to select external editor. Just wanted to leave a heads-up to anyone looking for an in-browser editor-this is not the one; at least it wasn't for me.
Very nice Rated 5 out of 5 stars
I like it when an extension does exactly what it is supposed to do, nothing more nothing less!
