Remember the Novell TID Finder page? Now there's a Novell TID Finder Firefox extension that works the same way - just enter a TID number and off you go! It adds the Novell site to the search engines in your Firefox browser, so you just select the Novell TID Finder from the search dropdown list. Don't be fooled by where the add-ons people misfiled it under Thunderbird add-ons, it's definitely for Firefox.
