Simple, Does Exactly What I Want Rated 5 out of 5 stars

This little add-on does exactly what I want it to, I code HTML emails and most clients disable images by default, so when I'm previewing an email I'm working on in Firefox this makes turning off images a snap to see what the users will first see when they receive one of my emails and let me code changes accordingly.

This review is for a previous version of the add-on (2.1.1-signed).
