🧑🏻‍💻 Usage

  • visit about:config
    • set toolkit.legacyUserProfileCustomizations.stylesheets: true
    • extensions.pocket.enabled: false
  • Go to Menu > More Tools > Customize Toolbar:
    • auto-hide downloads button
    • remove all flexible space
    • remove all icons
  • Open about:support, copy the path of the Profile Folder
  • open the terminal
  • run cd /path/to/profile
  • run git clone https://codeberg.org/tommi/firefox-monoline.git chrome

🚗 Compact mode

The built-in Firefox “Compact mode” vertically compresses the navigation bar by slightly reducing its height. To activate it:

  1. visit the about:config page;
  2. search for browser.compactmode.show and change it to true;
  3. go to Menu > More Tools > Customize Toolbar, set density as “compact”.

In order to use Compact mode with Firefox Monoline it is necessary to change some parts of userChrome.css:

  • remove the first 9 lines (delete urlbar-container and urlbar styling)
  • in line 34, change the value to -36px !important
