Firefox nicht von GTK-Theme betroffen

Wie kann ich Firefox dazu bringen, das Adwaita-Design wie alle anderen Apps zu verwenden?

Gut:

Schlecht:

Machen Sie Webseiten vorzugsweise auch dunkler.

Sie können Gnome Tweak Tool verwenden, um das dunkle Thema für alle Anwendungen zu verwenden:

ABER

Firefox verwendet GTK2. Gnome Tweak Tool bearbeitet nur die GTK3-Einstellungen, daher müssen wir die /usr/share/themes/Adwaita/gtk-2.0/gtkrcDatei bearbeiten .

1. Zunächst sichern wir unsere gtkrc-Datei

   sudo cp /usr/share/themes/Adwaita/gtk-2.0/gtkrc /usr/share/themes/Adwaita/gtk-2.0/gtkrc.bak
   

2. Kopieren Sie als Nächstes Folgendes und ersetzen Sie Ihre vorhandene gtkrc-Datei:

   #Color scheme originally contributed by Franco Gotusso as Clearlooks-DarkOrange 
   # Based on Clearlooks-DarkCoffee by Chibi and edited by bvc as Clearlooks-DarkCoffee2

Bei neueren Firefox-Versionen (67) ist die Unterstützung für dunkle GTK3-Themes immer noch Blödsinn. (Formular-Widgets werden häufig mit falschen Farben gerendert.) Hier ist eine Band-Aid-Korrektur:

Goto: about:config 
Add String entry: widget.content.gtk-theme-override
Set value to: Adwaita:light
Goto Customizations: choose Dark theme
