Almost perfect Rated 5 out of 5 stars

It's faster than a lot of other image zoom add-ons I've used and has a nice amount of options, too. It's great that it can show you an images dimensions, but if it could show the aspect ratio too, it'd be fantastic.
It does zoom on .gif and .webm filetypes as well as the standard .png and .jpg, so that's great,

Works perfectly, but... Rated 3 out of 5 stars

Please make it compatible with multiprocess!

ONCE UPON a TiME... iT WORKED... Rated 2 out of 5 stars

NO MORE... eg. on Facebook, it either does NOTHING ATL ALL, or, show a thumbnail as ... a thumbnail AGAiN (maybe +10% zoomed).
In other pages (sites) workes 50-50%:
in some, it does; in some, it doesn't!
It's a pity! BECAUSE it's been more than a month as above, and NO RESOLViNG UPDATE YET, to remedy this.
(I'm afraid, "imagus" alternative addon, behaves pretty much the same.)
Let's see, whose seveloper fixes its own FiRST? ...

Stopped working on Facebook photo posts. Rated 4 out of 5 stars

It's without doubt my favourite add-on - and I use it all day long -
but it's NOT working again on Facebook.
Any normal photo posts will not POP anymore - but outside links still work.
It's working OK on Google Images and other sites - but on Facebook - not.
No doubt some change to the Facebook code has crippled it for now.
Could you please have a look and update it - and get it working again.
Thanks David.

YEAH. NO. IT IS STILL NOT WORKING Rated 2 out of 5 stars

I love this add-on, but it has stopped working on Amazon, Pinterest, YouTube, Tumblr, Facebook, & I don't know where else. I've temporarily switched to using the add-on "Imagus", until the creator of Thumbnail Zoom Plus can update.

Indispensabile Rated 5 out of 5 stars

Una delle estensioni più utili in assoluto. Una volta che lo si inizia ad utilizzare non se ne può più fare a meno. Non disturba e si disattiva/attiva in un clic. Perfetto!

Good add-on, but not working with Reddit Media Rated 3 out of 5 stars

This is a good app that works as advertised except for Reddit media. More and more images are being hosted on reddit's own servers as opposed to imgur and it would be nice to have those included.

Not working with Pinterest Rated 2 out of 5 stars

FF 49 (not ready to migrate) and Thumbnail Zoom Plus 4.1. Was working previously and then all of a sudden stopped working with Pinterest Home page. No Zoom icon and no zoom. :( Works when I click on a Pinterest thumbnail in a new tab. Zooms then but not from https://www.pinterest.com/. I don't use HTTPS Everywhere to conflict. Sent a msg to dev on FB but no reply. I really need it to work. Anybody know?

Thanks!
