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.

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

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。

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).

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