While browsing Firefox extensions the other day, I happened upon the TextMarker extension. WOW, what a great tool for students to use while researching the web. Students can highlight text as they read a web page. Then when they are finished they simply right click over the highlighted text and copy just the parts they have highlighted to their notes. The best part is when the student pastes the highlighted text that it automatically puts the source web site with the copied text.
Another great use of Firefox!
