Zotero [zoh-TAIR-oh] is a free, easy-to-use Firefox extension to help you collect, manage, and cite your research sources. It lives right where you do your work - in the web browser itself.
This browser add-in reduces clutter and visual distractions on a page. It enables text readers such as Click Speak (Firefox) to work better. It could also be used to strip iffy ads from websites teachers want to use with students. In addition, Paul Hamilton reports that it also strips clutter from pages you're importing to Kurzweil using the KESI Virtual Printer. Wow!
