Reference for longdesc display in Firefox browser

I thought the Web developers and Web accessibility evaluators in our circle 
might be interested in this.

The Mozilla Firefox browser [http://www.mozilla.org/products/firefox/] 
supports an extension called "Longdesc (v. 0.2)"  that, with the right 
click of the mouse, lets you bring up a longdesc page if one is associated 
with an image.

If you have Firefox installed, go to the Tools menu, and select 
Extensions.  A window showing your currently installed extensions 
opens.  Select "Get More Extensions".  Select "Miscellaneous" from the 
Categories and look for "Longdesc 0.2".  On my desktop it was on the third 
page of the search results.
