How to use system GTK3 theme in Firefox 102 ESR?

Setting `widget.non-native-theme.enabled` to false no longer works; I still get Firefox's default styling for controls and widgets.

I use a custom GTK3 theme in my environment that I want to apply to Firefox. The above setting works in 91 ESR, and broke with the upgrade to 102 ESR.

A custom user chrome stylesheet would be too painful.

Note: You can revert page styling to defaults in View -> Page Style -> No Style.

102.1.0esr, Debian testing, Xfce 4.16

Interesting. Maybe it was deprecated for the better.

I was thinking of Firefox adapting styles from the GTK theme CSS file to their own browser styles, or something like that.

So I guess for now it's a no.
