It seems to work on my device.
Try to install theme in the latest version.

Is the accent color applied if dark mode is active? Just to clarify, I mean the accent color from windows. In the following screenshot you can see it's applied on the about dialog (brown titlebar) but not on the main window.

If it works again in 104 that's great. I'll test when it hits beta and let update the issue.

I think it's going to be a breaking change.

I have now a little of a strange problem. It doesn't matter if I make a new profile, refresh my profile or install firefox dev on window 10.
The problem is that when -moz-accent-color is set for a variable, like --uc-accent-color: -moz-accent-color firefox loads the variable, but strangely doesn't set its accent color.
If I change -moz-accent-color to a color like red it works, but -moz-accent-color doesn't work.
-moz-accent-color only works when applied directly, without using it via a variable.
The problem occurs not only at the titlebar but also when userContent.page.proton_color.system_accent is set true

(I have FireFox 102.0.1)

Made a new profile with the default .css folowing your intallation guide vs with it should look
