Currently Firefox does not support color correction for videos. This leads to very over saturated videos on wide gamut displays like on the MacBook Pro. Safari and Chrome do support full color correction.

There are multiple bugzilla entries about this issue. One is 7 years old: https://bugzilla.mozilla.org/show_bug.cgi?id=789871 https://bugzilla.mozilla.org/show_bug.cgi?id=1476919 https://bugzilla.mozilla.org/show_bug.cgi?id=1500775

Generally, the default settings for the color correction mode are not very useful as also images and CSS colors become over saturated. This however can be manually changed by setting color management mode to 1.

Since more and more screens and notebooks have wide gamut displays, it would be nice to see that this is taken care of.

Usually color gradation is video driver related issues or failing video hardware causing the issues of mismatch colors.

WestEnd, it is a general issue you can observe on any wide gamut screen (I tried multiple Macs) with firefox. Safari and Chrome based browsers are not affected. Some people might not notice the issue, because videos are watchable fine. It's just that all the colors are a bit over the top, which makes them seem unreal. However, the strength of the effect depends on how big the differences of the color spaces are. (Wide gamut screens have a bigger color space than SRGB)

With the default settings the same happens with CSS colors and images that don't include a color profile. As I understand it, firefox just assumes that the color profile of the screen and the content matches. Or to be more precise, that both are SRGB. Only images that include a color profile are correct by default. Even though CSS should be interpreted as SRGB according to the standard and as such be corrected on a non-SRGB screen.

I don't notice the issue with standard settings installs. If there is color issues then proper equipment is need to test for color degradation. I use Windows 10 and color variation doesn't show up on my side.

If you are using a wide gamut screen, you can see the differences on this site: https://cameratico.com/tools/web-browser-color-management-test/

There is also a guide to change the settings so that CSS colors will be corrected. https://cameratico.com/guides/firefox-color-management/ (Other browsers do this by default)

But even with those settings, videos will not be corrected. It appears that this is a missing feature or bug in firefox.
