Legal research plugins for Firefox

One of the nice features of the Firefox browser is the ability to customize its search bar with search plug-ins for a variety of sites. Now, Cornell Law School’s Legal Information Institute offers a selection of five LII Search plugins. Of the five, one allows you to search the entire LII site. The others search specific portions of LII: the U.S. Code, Wex (its legal encyclopedia), the annotated Constitution or recent federal circuit opinions.

Note to LII: The Wex plug-in seems to have a glitch. On several tries, I received the response, “badly formed search query.”
