FYI in firefox (62.0.2) some 'before' images look different.

In chrome they look identical. Perhaps the source images included gamma information?

CRS-4 Mission Launch by SpaceX (less contrast, less color saturation in 'before')

Jellyfish photo by 贝莉儿 NG (much lower blue saturation in 'before')

Yes, some of the source images are tagged with ICC color profiles.

It looks like Firefox still does not treat untagged images as sRGB and the difference on wide-gamut monitors may be noticeable.

That was a matter of an option switch. It should be fixed now. Thanks.
