Got this to replace the Image Zoom extension after the FF57 update. I think it's even better thanks to some added functionality. And the 2.2 update to swap the mouse clicks to make them more familiar for people like me coming from the Image Zoom extension makes it even better.

This Used Be the Best Add-on and Probably by Far My Most Used. Since the latest update, it has been totally destroyed. I deleted it, but there is no replacement. Put it back to the way it was or, I can't actually believe that I'm about to type it........I'll start using Explorer!!!

it works very good. But it dont work with the plugin "snap links" together.

Zoom Image is no improvement over just holding down the Ctrl key and scrolling the mouse wheel.

It is not worth the memory it takes up

Very "buggy" when used on facebook ... scrolling on facebook becomes "jerky" after zooming an image

legacy image zoom was great. this one sucks

Uma bosta... É necessário clicar, uma combinação louca de teclas... Gif's não são exibidos... Um lixo.

Floating Zoom and Zoom shortcuts don't work. (FF59)
Everything else works.

以前使っていた"Image Zoom"の完璧な代替アドオンです。それに、より高機能で多くの画像のズームができました。
他にも多くの類似アドオンがありますが、これが一番直感的で快適に扱えました。

Fit to window Right click + Middle click not work in Windows 7 Firefox 56.0.2 64 bits

Firefoxのデフォルトである縮小表示をabout:configでoffしてあったのが、今回のバージョンアップで更に無効化されて毎回縮小表示になってしまいます

The new version doesn't work anymore. Neither in FF56 nor in FF57 Quantum. Neither unter Windows, nor under Linux.

Great addon, with the newest 2.0 version it's even better than the abandoned Image Zoom. There's only one annoying bug - when zooming images in the Image Viewer the upper part of the image is cut off and you have to zoom out to see it.

From version 2.0 it becomes perfect, with all features I need and just one of "must have" addons

My replacement for 'MouseZoom'. And Zoom Image works even better. IMO the best zoom add-on available for FF.

Worthy replacement of Image Zoom.

I like the add-on. Works as intended!

Unlike Thumbnail Zoom Plus, images don't jump at you when you hover your mouse over them.

Awesome addon. Works as advertised in latest version of Firefox (55).

IT HASN'T IN QUITE A WHILE. IF IT'S NO LONGER SUPPORTED I'D LIKE TO KNOW SO I CAN DELETE IT.

Woot its has been here, I had looking for a long time.
Thx alot ;D
