Great extension, thank you!

Love this addon! The only drawback is, it doesn't work on Reddit

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.

Two things that keep me from switching from the now-unsupported Better Image Viewer: the dark theme isn't the same as firefox's default, and the image can't be made to fit the entire window (not fullscreen, just browser window width or length). Even better if the latter can be set to default.

Perfect. Works exactly as it says. Gonna recommend this to everyone
