Rated 3 out of 5 stars

great addon but still lacks the ability to blacklist the function on certain sites not listed in the preferences menu. a simple box where you can paste the url of the site you want the addon to not work on would suffice. also if you implement this make sure to reference the url of the tab not the url of the image you are hovering over.

This review is for a previous version of the add-on (2.7.1-signed).  This user has a previous review of this add-on.

You can try the blacklist feature in the beta version at https://addons.mozilla.org/en-US/firefox/addon/thumbnail-zoom-plus/versions/
