This extension is unironically better than any built-in photo editor/viewer Windows ever had by default. 99% of the things I want to do with the picture, I can do while it's still in the browser.
Crazy good.

Perfect image viewer! I really like the zoom its very convenient. The rotate feature for those wrongly portrait photos in landscape, the editing everything is excellent. 100% recommended addon

Great extension, thank you!

Amazing addon. If there is a way to, please allow this for installation in android. It is working pretty well, but needs a specific third-party firefox fork to install.

5/5 for being the only 'image viewer' extension out of the dozen I've tried with the ability to pan/move the entire image within the space of the browser, instead of it being locked in the center.

Does exaclty what it says and that in a very smooth way.

best viewer in ff
