People with FF 54.0.1 or Higher Downgrade to version 4.1! Rated 4 out of 5 stars

Only version 4.1 is compatible with FF 54 to 56, click on the "View other versions" text on this page and scroll down to version 4.1.
Before you install version 4.1, dont forget to uninstall the previous plugin even if its in disabled form, and restart firefox.
Install the new one only after you removed the old one and restarted.

Still working Rated 5 out of 5 stars

Still working for me though I'm not on FF 55. I stayed on 54 until this webextension shite has found a solution.

WAS GREAT... Rated 1 out of 5 stars

BUT IT HASN'T WORKED IN QUIT A WHILE. I CHECKED MY PLUG-INS FOR UPDATES AND IT SEEMS THIS ISN'T WORKING WITH THE CURRENT VERSION OF FIREFOX. IRONIC THAT IT HAS THE NEW "LEGACY" ICON IN THE ADD-ON PAGE.
OH WELL.

Works ok, no e10s support Rated 4 out of 5 stars

Just a reminder, you can install Chrome addons using Chrome Store Foxifier. Ironically, that's the only way I could find a replacement addon that works with Firefox's multi-process feature.

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.

Not working on Pinterest Rated 5 out of 5 stars

Awesome. Must have in browser.

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!
