Kiki picture exported with sRGB chunk.

Okay, so I’ve compiled Krita to save the SRGB chunk. The sRGB chunk is a
switch, like a lightswitch, to tell applications the png file is absolutely
100% certainly a sRGB image. There’s NO profile information involved.

I have saved the Kiki image with this sRGB chunk, and double-checked with
pngcheck whether it had only the chunk saved.

If you open this file, you will notice it looks EXACTLY the same as the sRGB
embedded profile file.

I do not think Firefox makes any exceptions for any sRGB profile, as that would
mean it would treat the sRGB chunk differently from this supossed canonical
sRGB profile. As this would be incredibly stupid, and I do somewhat respect the
Firefox programmers, I do not think they treat the sRGB chunk any different
from any generic sRGB profile, and would in fact dare to say there’s no
difference between files with an sRGB profile and an sRGB chunk for Firefox.

In short, all files marked with colormanagement meta-data will get the ugly
distortion given by firefox due to the ColorD default profile.

What I suspect might be happening on Windows is that both the ‘use monitor
profile’ needs to be ticked, as well as the monitor profile loaded into Krita
and selected from the list.
If you had Windows’ colormanagement use your display profile, then Firefox
probably grabbed it, while, without those options, Krita would still use the
default sRGB profile to manage it’s canvas.

If setting Krita to explicitely use the right profile fixes the issue, then we
have a usability issue on our hands that indeed needs to be fixed as well.

(Also I just discovered I accidentally disabled the wole option instead of
unchecking by default... whoops, gonna fix that now)
