Firefox Addons - Basic things you should know

What are Add-ons?

Add-ons are small pieces of software that can add new features or tiny tweaks to your Firefox. There are five types of Firefox Add-ons; extensions, themes, dictionaries, search engines and plugins.

Extensions

Extensions are small add-ons that add new functionality to Firefox, from a simple toolbar button to a completely new feature. They allow you to customize Firefox to fit your own needs and preferences, while letting us keep Firefox itself light and lean.


Themes

Themes are like new clothes for your Firefox. A theme can change only a few colors, or every piece of Firefox's appearance. It's another great way to personalize Firefox to your tastes.


Dictionaries

These dictionaries work with the spell-checking feature in Firefox.


Search Engines

Add these search engines to the Search Bar in the upper-right corner of Firefox, for quick access to your favorite search sites.


Plugins

Plugins help your browser perform specific tasks like viewing special graphic formats or playing multimedia files. Plugins are slightly different from extensions, which modify or add to existing functionality.


Hmm..I think that I should post this entry earlier than this one. But, never mind. I hope that this basic information are really useful for you.
