Exclude Firefox from being themed

[PhilippKosarev]

Prerequisites

• I performed a cursory search of the issue tracker to avoid opening a duplicate issue.

Checklist to make sure the issue is not on your end

• I have made sure that I do not have multiple versions of the theme installed. Only one version should be installed in either ~/.local/share/themes or /usr/share/themes or ~/.themes
• The file ~/.config/gtk-3.0/gtk.css does not exist. (If it does, backup and remove it.)
• I have logged out and in again.
• Dark theme only. I have enabled adw-gtk3-dark in gnome-tweaks AND set the appearance to dark in gnome-control-center
• The flatpak theme is installed org.gtk.Gtk3theme.adw-gtk3 and org.gtk.Gtk3theme.adw-gtk3-dark
• The app I'm having an issue with is an actual GTK3 app and is not coded using another toolkit like GTK2, GTK4, QT, etc.
• I have created a new user profile without any modifications except adw-gtk3.

Description

Hello, I have the Firefox GNOME theme installed, so Firefox already looks like a native gtk4+libadwaita app. Is it possible to exclude Firefox from being themed?

OS and version [e.g Fedora 37]

Fedora 41

Adw-gtk3 version. Also specify your installation source. [e.g tar.xz, AUR, git main branch]

v5.6 from gitub releases

GNOME version

47.2

Application name and version (If the issue is with an app.)

No response

I've removed most of the color customizations as they're probably no longer needed. Some minor fixes will have to stay though.

Thank you :)

Another theming issue is that I want my gtk3 apps to use the dark theme, but then that also prevents Firefox from using the light theme, any way to avoid that?
