Using add-ons

Firefox can do a lot more than your average browser. One of the ways you use Firefox for something other than just browsing the web is to install add-ons. Firefox add-ons are small pieces of software that add new features or functionality to your installation of Firefox. Add-ons can augment Firefox with new search engines, foreign-language dictionaries, or change the visual appearance of Firefox. Through add-ons, you can customize Firefox to meet your needs and tastes.

The installation process is the same for Firefox on any Operating System, so you can install them on Windows, Linux, or MacOSX (you must first have Firefox installed!).

What is a Firefox Add-on?

An add-on is a software module which lets Firefox do something more, or do things differently. To use an add-on, you must download the module and install it. Then Firefox gets the functionality of this new module.

There are several types of add-ons: extensions, plugins, and themes.

• Extensions provide additional functionality to Firefox.

• Themes change the visual appearance of Firefox.

The functionality available from add-ons is quite wide. You can add dictionaries to Firefox, change the look of Firefox, display the time in different countries in the browser, or an add-on might suggest other websites you can visit that are similar to the one you are looking at. 

To see available add-ons, see the Firefox add-ons page:
https://addons.mozilla.org/firefox/

The list of Add-on categories are here :

https://addons.mozilla.org/firefox/browse/

You can browse the list and see whats available. 

• Warning

It is possible to create add-ons that can do a number of things you might not like. An add-on can read a lot of information from your browser as you browse sites or might use various tricks to get, add, alter, or destroy data on you have on your computer. It is for this reason that you should never install an Add-on unless it is from a trusted source. We recommend that you never install an add-on for Firefox unless it is available from the official Firefox add-on pages.

Acquiring add-ons

You can acquire new extensions and themes through Firefox itself:

Finding and installing add-ons

1. In the Get Add-ons panel of the Add-ons window, search for an add-on by typing the search term in the Search All Add-ons field, then press EnterReturn. A list of add-ons matching your search term will display.
   
    
   
   
2. To begin installing an add-on, select it and click on Add to Firefox....
   
    
   
   
   • You may be required to review and accept the End User License Agreement. To continue with the installation, click Accept and Install.
3. Firefox will then fetch the add-on, and display the Software Installation window. To begin the installation, click Install Now.
   
     
   
   
4. After the installation is complete, you must restart Firefox to start using the new add-ons. To restart, click Restart Firefox that appears after installation is complete.
5. When Firefox restarts, the installed add-on is displayed with previously installed ones.

More Ways to Find Add-ons

You can also browse and install add-ons by clicking on Browse All Add-ons, which will take you to the Firefox Add-ons page.  By default, the page features top-rated Firefox extensions. There are several ways to specialize your search.

Installing an Add-on

To begin installing an add-on, click its name on the page. Detailed information on the add-on is displayed.

• Firefox automatically verifies add-ons compatible with your version. If the button is grayed out, the add-on is not compatible with your version.
  

To install the add-on, click the green Add to Firefox button.

• You may be required to review and accept the End User License Agreement. To continue with the installation, click Accept and Install.

After the installation is complete, you must restart Firefox to enable the add-on. To restart, click Restart Firefox at the bottom of the Add-ons window. When Firefox restarts, the installed add-on is displayed with previously installed ones.
