This is a great add-on with useful bunch of features. I loved the binding of right mouse key with scroll-wheel for image zooming.

My problem with the add-on is for some unexplainable reason it breaks Firefox XML viewer and instead of viewing XML file it only views the content of XML (the text nodes).
For me as developer is unacceptable and after years of using it I decided to remove it for now. :(

Is there any way you could add customization to the keys? like I could make it left click instead as I use a left handed mouse :)

Excellent addon. Only 4 stars because shortcuts cannot be changed in FF addons page. Although this is well thought-out, not everyone find default settings as useful.

almost everything works as expected, but 3 things force me to subtract 1 star:
1) most important and most annoying: when holding right click and scrolling the zoom works but also the entire page scrolls, I remeber this working differently in the past (ie. page content stood still - not scrolling - when zooming the image)
2) minor but stil quite annoying: rotate left/right options from context menu should be located in the root menu, not inside a submenu; I'm using this quite often and it's very annoying to click so many times just to rotate the image
and no, you can't just do it with the scroll wheel, because the entire page freaking scrolls - as described above
3) minor but just feels backwards: currently context submenu for rotate has options "rotate right" and "rotate left" in the wrong order - it's much more intuitive for "rotate left" (counter-clockwise) to be first and "rotate right" (clockwise) - second

other than that, the plugin is mighty useful, especially on 4k screens to zoom in on thumbnails on many pages.

thank you.

It would be amazing if you could alter images while scrolling through reddit, without needing to click on the post first!

Fantastic add-on for viewing images. Works wonderfully in Windows. Please, someone, port this over to Linux! This is one of my favorite add-ons!

REGARDING : This review by 12503762, 8 mths ago :

Would it be possible to add Base64 image support
(the data:image/png;base64 type of files for example)?
Also this extension has the same bug as the old ImageZoom extension,
on some images when you have them directly open in the page (direct link to image file),
when you zoom in it progressively crops the top of the image you can't see it at all.
Here is an image to show what I mean :

with this big image, depending on actions I do (direct zoom with clicks combination or mouse wheel)
It happens that the top of the image is not visible anymore, image seems to start from the middle of it.

What I (Oby) noticed is I can right click on the photo image of Bryan Cranston that appears after I use
"Zoom Image by Amu" 2x zoom, & drag it it down, then
the full TOP of the picture also drags into view.

I don't know why the scroll bar won't allow me to get to the top.

Maybe it's to do with Firefox screen size handling / zoom,
versus CSS-based screen-size handling / zoom.
Well, at least I took the time to make this post. B^)

I'm not sure what information to provide or if this place is suitable to let you see the message.

Great replacement for the old Image Zoom I used to use. However, I use it mainly for web development to check the flow of a webpage around images in a responsive nature. The problem is that when you zoom the image, it pops out of its html container and breaks the flow of the document. It is "floated". When zooming out, it behaves nicely, the image container reduces, and the rest of the page flows around it.
Zooming out is OK. Zooming in is the problem.
Could you add an option to allow enlarging the image without "floating" the image, to also increase the size of its container in the html flow?

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