It isn't too good Rated 2 out of 5 stars

It needs more zoom, it only duplicates the image with a little or no zoom at all. It's not useful to me.

Let me know when it works on ALL sites Rated 1 out of 5 stars

Was hoping for Hover Zoom like Chrome has, works on all sites. Oh well.

The same here!

"Installed to use with Facebook - doesn't do me any good. It claims to zoom to full-size image but it just makes the thumbnail a little larger"

Look at the function of FB Photo Zoom für Google Chrome, it does much better!

I agree with Lucidium. Although this add on is great, I only wanted it for Reddit. I'm shit out of luck.

Not Working on Twitter Anymore Rated 4 out of 5 stars

This add-on stopped working on Twitter once Firefox 8.0 released. I love this add-on and Twitter was my main reason for getting it. Please fix this!

Needs to work on all sites Rated 2 out of 5 stars

There is a great thumbnail viewer for chrome that works on every site, why cant this one do the same?

Rated 3 out of 5 stars

this add-on, for some reason, isn't maintained anymore.. at least on Linux platforms.

i use the renewed Thumbnail Zoom Plus (look here: https://addons.mozilla.org/en-US/firefox/addon/thumbnail-zoom-plus/ )

since the Plus one isn't yet reviewed by Firefox/Mozilla (as of Nov. 2011) you're using quite a beta version of the add-on.. it's close to perfect, but there are issues.. like overlapping the cursor and so forth..

enjoy :)
