By -

First of all we understand what is the meaning of Firefox add-ons and use of them.

Firefox Add-ons is a very popular feature to the firefox browser. It allows a user to change the behavior of the browser, often in the form of extra toolbars, context menus, themes or UI to customize the browser.

Add-ons is an installable file having an .XPI (Cross-Platform Installer Module) extension. Many of us are aware and use many of the well know extensions. To name a few, we have Web Developer, Error Console, Firebug, Facebook Toolbar, Alexa Toolbar and many more.


Types of Add-ons:

  • Extensions
                       Extensions modify the way Firefox works.
  • Appearance(Theme)
                       Themes modify the Graphic User Interface – the appearance of the browser window.
  •  Plug-in
                       A plugin is used to incorporate third-party programs (media players, PDF readers, etc) into the program session.Plugins are the “links” to external programs that handle files that Firefox doesn’t, like audio and video such as Flash or Java, or document platforms such as PDF files.
Some of the plugins that we use or at least we know- Realplayer Plugin, QuickTime Plug-in 7.5.5


  • Adding New Features to browser
  • Modify How User Views The Web Browser using Themes


Benefits of using Toolbar:

  • Immediate Access
  •  Self-explanatory
  • Recognizable and distinguishable
