Save desktop space in Firefox CSD mode in Debian 10

In Mozilla Firefox, which is pre-installed on most Linux distributions, there is a title bar above the tab area that takes up more space than necessary.

However, a feature has been added in Firefox version 60 that makes better use of screen space by adding a space-saving title bar. This feature, known as client-side decoration and often abbreviated as CSD, combines the main title bar and the Firefox tab bar into a single bar. This gives Mozilla Firefox a neat and compact look. You can access all options, such as Minimize, Maximize, and Close from a single tab bar.

The client-side decoration feature can be easily activated from Firefox’s configuration mode. In this article, we will show you how to enable the client-side decoration feature in Mozilla Firefox on the Debian operating system. We will use Debian 10 to explain the procedure described in this article, but you can follow the same procedure for other distributions.

Here is the standard view of Mozilla Firefox. You can see a separate title and tab bar at the top of the browser window.

Enable CSD (Client Appearance) mode in Firefox

Now we’ll see how to enable the client-side decoration feature in Firefox so that it looks better on the screen. Thus, in order to test CSD, you need to install Firefox version 60 or higher. If you are already using a previous version of Firefox, only upgrade your browser to version 60 or later.

Step 1: To enable CSD, first launch the Firefox browser on your system.

Step 2: Then click the hamburger icon in the upper right corner of the Mozilla Firefox window to open the main menu. When the menu appears, click on Tune,

The settings tab opens in Mozilla Firefox.

Step 3: You will see a flag below marked as Title bar. This check box is selected by default. Uncheck this box and click Performed apply changes. You can see the screenshot below for a clear understanding.

Changes will take effect immediately.

As you can clearly see, the client-side decoration feature gives your browser a compact look by combining the title and tab bars. This gives a compact look and also provides a larger window for the client and less for the browser itself.

Now compare the screenshot below with the one above without turning on the CSD. You can see this decoration feature on the client side.

That is all there is to it! We learned how to enable and try Firefox CSD on Debian OS. If you no longer like this feature, Firefox still suggests returning to the traditional Mozilla Firefox window, again checking the box marked as Heading.
