Review for Thumbnail Zoom Plus by TealShift
Rated 5 out of 5 stars
It's really a time saver, and I use a similar addon in Chrome, though it's funny because the Chrome addon has support for DeviantArt links, but this one doesn't. This addon makes up for it by supporting youtube better though.
What I'm saying is this is begging for DeviantArt support!
