A Firefox extension or add-on. Enables teachers to create a "trail" through several web sites for your students to follow. "Sticky notes" with the author's comments, notes, instructions, etc. are placed on any web page, along with your next and back button. This links the pages together, creating a sequential path for navigating the trail. Students need only click YOUR "next" button to proceed to the next site rather than returning to some sort of index. Visit Trailfire's homepage to sample some of the trails others have posted.
