Firefox extensions, also known as add-ons, are small pieces of software that add new features or functionality to your Mozilla Firefox browser. They can enhance your browsing experience by adding tools for privacy, productivity, social media management, and more. Adding and removing these extensions is a simple process. Here’s how you can do it.

Adding Firefox Extensions:

1. Open your Mozilla Firefox browser.
2. Click on the menu button in the upper-right corner of the window. It looks like three horizontal lines.
3. Select “Add-ons” from the dropdown menu. This will open the Add-ons Manager tab.
4. In the Add-ons Manager tab, search for an extension by entering its name in the search bar or explore available extensions by browsing through categories.
5. Once you find the extension you want to add, click on its name to view details.
6. Click on the “+ Add to Firefox” button to install the extension.
7. A permission window may appear, listing the data and functions the extension will have access to. Review these permissions carefully before proceeding.
8. If you agree with the permissions, press “Add” to complete the installation.

After installation, some extensions may require you to restart Firefox or they might be ready to use immediately.

Removing Firefox Extensions:

1. Open your Mozilla Firefox browser.
2. Click on the menu button at the top right of your browser window (three horizontal lines).
3. Select “Add-ons” from the dropdown menu.
4. In the Add-ons Manager tab, find “Extensions” on the left-hand side of the screen.
5. Look through the list of installed extensions until you find the one you wish to remove.
6. Click on “Remove” or “Disable” next to the extension you selected – “Remove” will uninstall the extension completely while “Disable” will turn it off without uninstalling it.

Some extensions will be removed immediately without further prompts, whereas others might require a restart of Firefox.

It is important to note that only download extensions from trusted sources, such as Mozilla’s official add-ons website, to ensure your browser’s security.

By following these steps, you can easily customize your browsing experience by adding or removing extensions according to your needs and preferences in Mozilla Firefox.
