This article is going to show the basics on how you can change the way tabs can be displayed on Mozilla's browser especially if you want to replicate a Chrome feature whereby there's no scrolling tabs function.

Configuring the Scrolling Tabs function

By default, Firefox will not reduce the width of the tabs. You have the scrolling tabs function so that, the minimum width for the tabs will remain at 100px. If you do not like the scrolling function, you can ask Firefox to display all tabs in a single strip. This is an option you are familiar with if you are an avid Google Chrome user. You can also choose to show more tabs in a single strip by adjusting the width of the tabs.

How to disable the scrolling tabs function

  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. Type browser.tabs.tabMinWidth in the 'Search' bar and press 'Enter'.
  3. Double click on 'browser.tabs.tabMinWidth' and you will see a new pop-up window.
  4. Change the value to '0' if you wish to disable the scrolling tabs function. Otherwise, you can change the default value to a smaller value like 75 pixel in order to show more tabs in each strip.
