17.10firefoxgnomethemes
With the release of firefox 58 I decided I would give it a go after having used chrome for a very long time, and so far the transition has been seamless, however I came across a rather annoying problem, I use a dark theme, but for some reason the top bar of Firefox is white. I have enabled the dark theme in the firefox settings.
Is it possible to make that bar dark too?
Start Firefox with one of the following command:
env GTK_THEME=Adwaita:light firefoxenv GTK2_RC_FILES=/usr/share/themes/Simple/gtk-2.0/gtkrc firefoxThis will launch Firefox using the Simple/Adwaita:light theme, which is pretty basic and should blend with your Persona. You can try other themes, by replacing Simple with the theme name, but this doesn't work with all themes.
So far I have successfully tested with Simple and Redmond themes...

In firefox, you can change this configuration setting through the "about:config" command.
In the address bar, type in and go to:
about:config
Click on the "I'll be careful, I promise" radio button. And input in the following query into the filter:
browser.urlbar.clickSelectsAll
Double click on the entry to toogle its value between true and false. Select "False" if you want to place the cursor at the insertion point, and select "True" if you want to highlight the entire address bar on a single mouse click.
Here is a link to an article that gives some more useful "about:config" hacks:

Firefox has no control over the white bar you mentioned, it is dictated by your "Applications" (GTK+) theme.
To change the theme open (GNOME) Tweaks and go to "Appearance" section. Select a different theme (which has a dark title bar) for "Applications" under Themes.
You can get more themes from sources like GNOME-LOOK.ORG.
