How can I make firefox use Adwaita theme like all other apps do?

Good: good

Bad: bad

Preferably also make web pages darker as well.

  • You also want "Preferably also make web pages darker as well". I'm not sure that this is the job of gtk themes. For that, it's better to install the Stylish extension and a suitable user style from userstyles.org (or modify userContent.css).

  • I had the same issue with Firefox and other GTK2 apps, and solved it using this theme (note a version to match the shell is needed)

You can use Gnome Tweak Tool to use the dark theme for all the applications:

tweak tool - enable dark theme for all applications

BUT

Firefox uses GTK2. Gnome Tweak Tool only edits the GTK3 settings, hence we need to edit the /usr/share/themes/Adwaita/gtk-2.0/gtkrc file.

  1. Initially we backup our gtkrc file 

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

  2. Next copy the following and replace your existing gtkrc file:

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

style "clearlooks-default"

  • It is already enabled... You can see that on screenshot. My settings.init looks just like that as well.

    @Stormvirux, you wrote: "you will also have to Edit ~/.config/gtk-2.0/settings.ini". Are you sure that gtk-2.0 uses settings.ini? I thought it was only gtk-3.0 that does so.

    Oof, I went ahead and did this. It made Firefox sort of work in Ubuntu 3.10, but the titlebar was still white and the theme looked pretty bad in general and inconsistent with Adwaita. Bummer this won't get fixed for a long time.

    Sorry for the necro comment here. I found this Q/A to be helpful in this problem in Ubuntu Gnome 14.04, however I didn't use the code provided by Stromvirux (I tried it, but it just gave an old Firefox 4.0 look to it, rather than a dark adwita). I instead used the default gtkrc and just replaced the line with the gtk-color-scheme with the following: gtk-color-scheme = "base_color:#4F524F\nfg_color:#eeeeec\ntooltip_fg_color:#eeeeee\nselected_bg_color:#3465a4\nselected_fg_color:#eeeeec\ntext_color:#EEEEEC\nbg_color:#363B3B\ninsensitive_bg_color:#8c8984\ntooltip_bg_color:#000000"

On newer Firefox versions (67) GTK3 dark theme support is still rubbish. (Form widgets often render with wrong colors.) Here's a band-aid fix:

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

  • Can you describe the fourth step "Goto Customizations: choose Dark theme" a bit more? It's not clear on my end what that is about. Otherwise thanks for this suggestion.

on Debian bullseye I did the following:

  1. install Tweaks
  2. open Tweaks > Appearance > Themes: Applications "Adwaita-dark"
  3. open Firefox > Settings

3.1. > Language and Appearance: Website appearance "System theme"

3.2 > Colors > Manage Colors

3.2.1 > tick "Use system colors"

3.2.2 > Override the colors specified by the page with your selections above: Always
