Firefox not affected by gtk theme

Question

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). — , Aug 25 '13 at 11:14
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) — Wilf, Apr 24 '15 at 20:34

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.

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

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

It is already enabled... You can see that on screenshot. My settings.init looks just like that as well. — Mislav Blažević, Aug 25 '13 at 10:48
@MislavBlažević, I think you should find an Adweita theme for Firefox, or create a userChrome.css file for it on yourself. Firefox is not a GTK app, it’s just made compatible with it. — AliNajafies, Aug 25 '13 at 10:54
Editing ~/.config/gtk-2.0/settings.ini has no effect. gtkrc-dark file does not exist. — Mislav Blažević, Aug 25 '13 at 10:59
@MislavBlažević https://bbs.archlinux.org/viewtopic.php?id=116652&p=2 .The issue is gtk2 does not have adwaita-dark .You will have Download it separately .see the above thread — Stormvirux, Aug 25 '13 at 11:02
@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. — , Aug 25 '13 at 11:08
@MislavBlažević Is this whay you had in your mind?? http://img833.imageshack.us/img833/6711/x3kg.png.Or do you even want the pages to be dark? — Stormvirux, Aug 25 '13 at 15:03
@MislavBlažević ok That reqires editing your gtkrc file in /usr/share/themes/Adwita/gtk-2.0.I will edit the answer and post my gtkrc with steps how I implemented it — Stormvirux, Aug 25 '13 at 18:03
@Stormvirux One more thing. All text in comb-boxes and forms like this is unreadable because it is light gray on white. Any idea how to fix that? — Mislav Blažević, Aug 25 '13 at 19:56
@Stormvirux nevermind last comment! I figured it out myself. Thanks for this theme, I LOVE IT!! — Mislav Blažević, Aug 25 '13 at 20:14
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. — mlissner, May 02 '14 at 04:57
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" — mason81, Nov 06 '15 at 20:26

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. – Johan May 13 '23 at 15:04

on Debian bullseye I did the following:

install Tweaks
open Tweaks > Appearance > Themes: Applications "Adwaita-dark"
open Firefox > Settings

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

3.2 > Colors > Manage Colors

3.2.1 > tick "Use system colors"
