You have three ways to install GNOME Shell extensions.

1. Install GNOME Shell Extensions Using GNOME Tweaks Tool

Once you’ve installed the GNOME Tweaks Tool, you can install a package containing a minimal set of GNOME extensions, which will be available in Tweaks. First, make sure Tweaks is closed.

Then, open a Terminal window by hitting Ctrl + Alt + T, typing the following command, and pressing Enter:

sudo apt install gnome-shell-extensions

You must restart the GNOME Shell. Hit Alt + F2, type “r”, and press Enter.

Restart the GNOME Shell

To start Tweaks, click Show Applications in the lower-left corner of the screen.

Click Show Application in Ubuntu

Type “tweaks” in the search box and click the Tweaks icon.

Search for and open Tweaks

Click Extensions in the left pane on the Tweaks dialog box. You’ll see a list of extensions with descriptions. Use the ON/OFF slider buttons on the right to enable and disable the extensions.

Some extensions have settings you can change (gear icon) to customize the extension.

2. Install GNOME Shell Extensions in a Web Browser

The GNOME Extensions website allows you to find, install, and manage extensions for the GNOME desktop. The website is an alternative to using the GNOME Tweaks Tool to manage extensions.

When you visit the GNOME Extensions website, you’ll see a message saying you must install the GNOME Shell integration, which has two parts: a browser extension and a native host messaging application.

The message provides a link to install the browser extension or add-on. This link takes you to appropriate extension or add-on page for the browser you’re using. Click the link to go to the page and install the extension or add-on.

We’re using Chrome in our example, but you can install the extension or add-on in any of the following browsers:

Once you’ve installed the extension or add-on, refresh the GNOME Extensions webpage. Now you’ll see a message saying you need to install the native host connector.

Hit Ctrl + Alt + T to open a Terminal window. Type the following command and press Enter. The command is the same no matter which browser you’re using.

sudo apt install chrome-gnome-shell

Enter your password when prompted.

If you only want to view extensions available for the current version of the GNOME Shell, select Current version from the Compatible with dropdown list. Extensions made for older versions of the GNOME Shell might work in the current version, but not all do.

Select Current version in Compatible with dropdown list

To install an extension, click the title of the extension in the list. On the extension’s page, click the ON/OFF slider button on the right.

How to Disable or Uninstall GNOME Shell Extensions

Extensions enabled in the GNOME Tweaks Tool can be disabled, or turned off, using the tool. They cannot be uninstalled unless you uninstall Tweaks. To uninstall Tweaks, hit Ctrl + Alt + T to open a Terminal window, type the following command, and press Enter:

sudo apt remove gnome-tweak-tool

If you installed extensions using the GNOME Extensions website, you can use the website to turn off or uninstall those extensions. To turn off an extension, click the ON/OFF slider button so it reads OFF.

Only extensions installed on the GNOME Extensions website that are not available in the Tweaks tool can be uninstalled. You can tell which extensions those are by the white X in the red box icon to the right of the ON/OFF slider button. Click the X button to uninstall the extension.

Uninstall an extension on the GNOME Extensions website

Extensions installed using the GNOME Extensions site are also added to the ~/.local/share/gnome-shell/extensions folder. So you can uninstall these extensions, and any extensions you installed manually, by deleting the extension folders from the ~/.local/share/gnome-shell/extensions folder.

How to Get Update Notifications for GNOME Shell Extensions

The only way to know if an update is available for a GNOME Shell extension is to visit the GNOME Extensions website. But there’s an extension available, called Extension Update Notifier, that notifies you when there’s an update for an installed extension on your system.
