This is a great add-on and helpful for when I print articles or pages for use in class to limit the wasted paper. The latest version, though, has problems with the rendering of the format menu when changing text and layout. I hope that gets fixed in the next version. I am not sure if this is because I am on firefox beta. This add-on also functions better in chrome, generally, but I think these are due to limitations of firefox's print preview.

I am still having trouble with the format menu. The boxes are not aligned with the settings so it is difficult to adjust formatting.
