I built a Firefox extension that pulls in realtime web content based on the content of the page you are looking at. It takes the title tag of the HTML file and parses keywords from that to be used in the Collecta query. These terms change and update as you travel from page to page so you are always getting a live feed of things you are currently interested in.

The extension can be downloaded and installed from: box.net/shared/unbpecjpju
