media query to detect Firefox's default theme

问题

Is there any media query to detect if user is using Firefox's default theme

I have tried

@media (-moz-windows-default-theme: 1) {...}

but it is also triggered when I was on a custom theme (e.g. FD deep dark) The aim is to change some colors on the UI, but they don't look good on dark themes

You're using it incorrectly, here's the right way to use it :

@media (-moz-windows-default-theme) {...}
