Context Explorer

Context Explorer is a sidebar, Firefox plug-in that uses open-source desktop indexer--Regain, to automatically associate your local resources to the pages youre browsing. For example, imagine you're browsing your school account and need to open a document for a current class. All you need to do is click the file in your sidebar because Context Explorer has already found it. There's no need to waste time hunting through endless folders and drives.

Requirements:

Windows 2000/XP/2003 Server/Vista, Mozilla Firefox 2.0.0.9
