Zoom doesnt work. Not on reddit at least. On chrome there is anextension with the same name but by someone else. Works perfect there.

Works great. Very, very nice to see a larger image.

Simple and effective addon, with its companion "Image Forward" by the same developer constitutes an almost perfect mode to have slide show with series of pictures opened in fullscreen mode and background of preferred color.
For this utilization I would want in preferences the opportunities to eliminate the informations briefly shown when opening an image and to open the images directly in fullscreen.
Anyway personal and minor flaws.
Thanks.

Firefox Quantum 57.0.1

1. good start, but it misses the most important scaling mode - "no anti-aliasing mode" (many people would like original crispy pixelated images), that can be toggled via CSS code:
html > body > img:only-child {
image-rendering: -moz-crisp-edges;
}
2. it will be perfect if that extension could toggle "no anti-aliasing mode" only when image scaled is bigger than 100% - that way when images zoomed-out (or have resolution less than your display) will be anti-aliased, and zoomed-in images (or those have resolution better than display resolution) will be displayed in original non-smoothed view. If you don't understand that I mean you can check any Faststone viewer software and look for scaling options.

Finally an WE enhanced image viewer with rotate feature.
Please add the zoom wheel.
Thanks.
