What are Firefox Add-ons and which ones are the best?

Firefox Add-on’s are small extensions that add new functionality to Mozilla Firefox. They can add new features, toolbars, and are completely customizable.

The complete list of Firefox Add-on’s can be found here: https://addons.mozilla.org/firefox/

AIS MI6 also has a list of useful Add-ons for a developer/university environment. The page is periodically updated as extensions evolve, become obsolete, etc.

Favorite Add-ons:

  • AdBlock – Filter out advertisement and other annoying displays. https://addons.mozilla.org/firefox/10/ Plus it gets even better with Adblock Filterset.G Updater, so you will always get updated filter lists so you don’t have to create one yourself.
  • Forecastfox – Show weather forecasts. Can be set with many zip codes/areas. Nice for advance planning and when taking a trip!
  • IE Tab – embeds Internet Explorer in Firefox and allows you to easily refresh a page as it would appear in IE with the click of a button. For example, a user can use Firefox to install Microsft Updates through Firefox. For Exchange users, OWA appears with all premium features in Firefox with IE Tab.
  • IE View – Akin to IE Tab (above), but can open current Firefox page or link in IE specifically.
  • NoScript – Adds extra protection to Firefox by allowing scripts to run within a webpage from domains and webpages that you trust and designate.
  • Nuke Anything Enhanced – Just great! Removes a specific page element or selected elements. Fantastic for cleaning up a webpage prior to printing.
  • Tab Mix Plus – Can be a power tool for power users, but has a few options all can enjoy. For instance, has an option to undo close tabs, has a tab loading progress bar (akin to Safari), and retains a list of all tabs open on previous session (useful when closing for the day or the browser crashes).
  • CoLT – copy and translate links to other formats like MediaWiki, Textile, Confluence, etc.
  • CoScripter – “lets you create and share scripts to automate tasks on the web.”
