Dark Themes Ahead

Reminder to self: How to fix Firefox about:config when using a Dark Theme in Gnome or Awesome.

I use System76 amazing Gtk+ theme from Pop!_OS. It’s quite simple to set up on top of Ubuntu and use in Awesome:

    sudo add-apt-repository ppa:system76/pop
    sudo apt update
    sudo apt install pop-theme

I then use gnome-tweaks to select the Pop-dark-slim theme. Now, the problem is that certain text box inputs in Firefox is either completely dark or white and the text cannot be seen until you mark it. This isn’t specific to the Pop!_OS theme, Adwaita-dark is exactly as bad.

Here’s how you fix it:

1. Open about:config in Firefox
2. Create a new String value (right click), named widget.content.gtk-theme-override
3. Set a light GTK theme name as the value, i chose Pop
4. Restart Firefox

Thanks to Moritz Kammerer for blogging about this so I could find a solution.
