I was disturbed to find in a test for v2 and v4 icc support from the color.org website (International Color Consortium), "Is your system ICC Version 4 ready", which Firefox failed.
I found out that what the ICC refers to as "system" references browsers. My computer is an iMac OS X 10.13.6 and my Firefox is v93. The test is https://www..color.org/version4html.xalter. There is a link that brings the test up in PDF, which I think is necessary as the link itself seems to be only a picture.
Other photography sites have pointed this use of the word "system" out for, in my case, Safari and Chrome for instance. I tried Safari and ran the PDF test. It passed. I tried Firefox again (and again) it failed every time. Other people have had the same result, as in the following quote, "...Houston we have a problem...".
One of the most helpful websites I have found for this, mostly from fine photography sites, was
https://gregbenzphotography.com/photography-tips/how-to-setup-proper-color-management-in-a-web-browser. This website had six tests for browsers. Firefox passed every test except test #6. Using Safari, it passed all including test #6. You could try it with Chrome.
This website, and many others, suggested a Firefox enabling correction that starts with typing into a Firefox address bar about:confg click, and after some scary warnings, type in gfx.color_management.mode (set to 1), click, then gfx.color_management.enablev4 (set to true), click, then gfx.color_management.rendering_intent. (set to 1 relative colorimetric--or to 0 for us Philistines). Restart Firefox.
Didn't work, Firefox still failed. I tried this many times, same result. Read the last sentence of the Summary on that website.
I'm sad to do this, but sending my even relatively elementary images to an outside printer, using PDF/X1a to KDP or IngramSpark for instance, I'll use Safari because I don't trust what Firefox might do. If anyone knows a way for Firefox to pass muster with the ICC, I will gladly use it.
