Compact mode is not currently supported. For the recommended and supported experience, we encourage you to keep the normal density setting.

Starting with Firefox version 89, the compact mode density option was removed from the Customize panel. If you are an advanced user, it's still possible to activate it in the Configuration Editor (about:config page).

  1. Type about:config in the address bar and press EnterReturn.
    A warning page may appear. Click Accept the Risk and Continue to go to the about:config page.
  2. Find the browser.compactmode.show preference.
  3. Switch the toggle to true and then close the tab.
  4. Click the menu button Fx89menuButton to open the menu panel.
  5. Click More Tools.
  6. Choose Customize Toolbar.
  7. At the bottom of the panel, click Density.
  8. Choose Compact (not supported) from the menu options.
  9. Click Done.
