> effectively sidesteps the issue by making everything render to sRGB

Wow, that seems ... really unfortunate? So on macOS, if I open a nice photo from a friend that's tagged with AdobeRGB, Firefox will downconvert that to sRGB? I hope they don't bring that change to any other OSes!

You're right that mode 1 is flaky and could use some improvements (video, canvas elements, av1 which is treated as video by the decoder...) but converting wider gamut graphics down to sRGB seems like a clear step in the wrong direction.

By the way, Firefox passes all the tests in the article you linked to for me.

Honestly, I'd rather have consistent and accurate colors across multiple monitors even though it would be limited to sRGB. Most content on the Web is for sRGB anyways, so it's not like much was lost.

It's still much better than Windows though... I clamp my wide gamut monitor to sRGB because Windows is so infuriatingly inconsistent.

Firefox does not pass the second test for me on macOS.

Also, wow. How fast is the new Firefox?

Are you using the beta? If not, that's expected unless you have the mode=1 setting I mentioned in my top level comment. I have that set on Linux and everything works as expected. (I haven't tested this on macOS at all so it's possible the setting isn't even functional in Firefox 88 for Mac.)

I am using the Beta. Testing with both mode=1 and mode=2 causes a no purple tick to show on macOS.

Oh that? That's a different thing. You need gfx.color_management.enablev4 for ICCv4 profile support.
