First of all, I'd like to commend the team at Evernote for putting the FF plugin back on the roadmap. With the introduction of the developer version of Firefox, the usual gray icon is no longer visible in the monochrome toolbar (screenshot). Would it be possible to request a monochrome version of the icon as a configurable setting? I know it's a long stretch, but perhaps something to add given time (as a configurable option)? Cheers!
