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.

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.

Great extension.. But photo editor is not working right now.. A simple request to the developer: Is it possible to add a settings button to switch "always show details panel" . That would be very helpful..

best viewer in ff

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

best image viewer there is
