Checklist to make sure the issue is not on your end
[X] 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
[X] The file ~/.config/gtk-3.0/gtk.css does not exist. (If it does, backup and remove it.)
[X] 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
[X] 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
As of Firefox 125.0, the header buttons on the application's CSD are closer together than intended, when using adw-gtk3 (general, not specific to light nor dark.)
Top bar with CSD enabled and default Adwaita GTK theme:
Top bar with CSD enabled and adw-gtk3-dark 5.3-2 from AUR:
This issue is unrelated to any extensions. My only nonstandard configuration is using the "compact" density in Firefox, but changing the density setting does not affect CSD button spacing. The relevant issue on Mozilla's tracker, with some explanation in the comments, can be found here.
