Rated 5 out of 5 stars

Works great, but seems to still be broken for Pinterest.Running FF 19.0.2 and TZP 2.4rc4Edit: It's not working on any of the Pinterest URLs, http://pinterest.com/all/geek/ for instance. The Pinterest preference is checked, but it might be because I'm on Pinterest's new layout release. I don't know if it's live for everyone yet since I opted to upgrade early.

Edit: As of today, 4/3 it seems to be working for Pinterest again!

This review is for a previous version of the add-on (2.3.2.1-signed). 

2.4rc4 works in pinterest for me; what URL (page) is it not working on? Reply in the review or by email to firefox.add.on@davidadler.name. And make sure the Thumbnail Zoom Plus preference "Pinterest" is turned on.
