Firefox Add-ons

Page history last edited by Scott Frey 13 years, 5 months ago

Firefox add-ons are small extensions that give new functionality to complement the browser's built-in features, so that you can customize it to fit your own individual needs. 


This is a list of Firefox add-ons recommended by law librarians.  It was created by Bonnie Shucha, University of Wisconsin Law School, for a presentation at the CALI Conference of Law School Computing, June 2009.  If you would like to add to this list, you may contact Bonnie or request access to the CS wiki and add it yourself.


(Note: The beta version of Google Chrome now officially supports extensions.  While a list of recommended Chrome extensions would probably not yet be as long as a list for Firefox, development of Chrome extensions is occurring rapidly.)
