Rated 4 out of 5 stars

I love being able to simply hover over an image to have it enlarge. I only wish it worked on pinterest too. It's a favorite tool to use on image searches and fb, I really miss it when I'm on a site it doesn't work on.

This review is for a previous version of the add-on (1.6.0.1-signed). 

Pinterest is a good idea; I've added and it's now available in the 1.6.1beta1: The fix is released in 1.6.1beta1: https://addons.mozilla.org/en-US/firefox/addon/thumbnail-zoom-plus/versions/
