Rated 4 out of 5 stars

Creates a convenient button you can put on the Nav Bar to control the Firefox built-in checkbox Tools/Options/Content/ "Load Images Automatically"
Note: The Firefox Tools option doesn't disable _all_ images: on news.google.com, the thumbnails are still visible. Not this add-on's fault, though.

This review is for a previous version of the add-on (0.2.8).
