Firefox Qogir theme

A flat and clean theme for Firefox 60+

Preview

Qogir

Description

This is a bunch of CSS code to make Firefox look closer to Chrome theme.

Installation

Manual installation

  1. Go to about:support in Firefox.
  2. Application Basics > Profile Directory > Open Directory.
  3. Copy chrome folder Firefox config folder.
  4. If you are using Firefox 69+:
    1. Go to about:config in Firefox.
    2. Search for toolkit.legacyUserProfileCustomizations.stylesheets and set it to true.
  5. Restart Firefox.
  6. Open Firefox customization panel and:
    1. Use Title bar option to toggle CSD if is not set by default.
    2. Move the new tab button to headerbar.
    3. Select light or dark variants on theme switcher.
  7. Be happy with your new gnomish Firefox.

Enabling optional features

Open userChrome.css with a text editor and follow instructions to enable extra features. Keep in mind this file might change in future versions and your configuration will be lost. You can copy the @imports you want to enable to a new file named customChrome directly in your chrome directory if you want it to survive updates. Remember all @imports must be at the top of the file, before other statements.

Known bugs

CSD have sharp corners

See upstream bug.

Icons color broken

Icons might appear black where they should be white on some systems. I have no idea why, but you can adjust them in the theme/colors/light.css or theme/colors/dark.css files, look for --gnome-icons-hack-filter var and play with css filters.

Development

If you wanna mess around the styles and change something, you might find these things useful.

To use the Inspector to debug the UI, open the developer tools (F12) on any page, go to options, check both of those:

  • Enable browser chrome and add-on debugging toolboxes
  • Enable remote debugging

Now you can close those tools and press Ctrl+Alt+Shift+I to Inspect the browser UI.

Also you can inspect any GTK3 application, for example type this into a terminal and it will run Epiphany with the GTK Inspector, so you can check the CSS styles of its elements too.

GTK_DEBUG=interactive epiphany

Feel free to use any parts of my code to develop your own themes, I don't force any specific license on your code.
