Firefox V133 system color no longer shown at top

[rw330i]

Is this something that can be fixed via CSS? All of the gray at the top now really irritates me. I appologize if I may have posted this in the wrong area. Thank you.

It still is possible to get accent colors on Fx 133+:

about:config > browser.theme.windows.accent-color-in-tabs.enabled > true

userChrome.css or my_userChrome.css

#main-window {
  appearance: auto !important;
  -moz-default-appearance: -moz-win-borderless-glass !important;
}

I actually had a slightly different version in my_userChrome.css. I have to admit that it's been a very long time since I looked at that file. The fix this time was browser.theme.windows.accent-color-in-tabs.enabled > true. I wonder if it used to be true. I did keep the version I had been using. Thank you very much for your response.
