How To Make Firefox The Most Useful Web Browser There Is

Step 6 Adding Addons

Go to the tools menu again, select add-ons, and then go to the extensions tab of the window this time. Select "Get Extensions" And browse around. Install them the same way you install themes.

Here is a list of my favorites:
Meebo-Instant messenger without having to download anything... works with aim, google talk, msn, and a bunch more
BugMeNot-If you have to log in to something, for instance the New York Times to view an article, right-click, select BugMeNot, and it will log in for you with an already registered name.
DownThemAll-Massive Downloader...
Flagfox-Shows location of a site's server
Forcastfox-Weather in firefox
Remove It Permanently-Remove ads from a website, so whenever you go back *kapoof* no ads!

Look at the picture below to see how well Flagfox works...
