Tree diagrams are awesome.
Firefox is even more awesome.
What happens when you mix together this much awesomeness?
You get the History Tree add-on for Firefox. What does it do to your browser? You can use it to find any page you have visited quickly and easily. It also shows your browsing history as a tree of tabs, with thumbnail screenshots of the web pages in every tab you have opened.
Usage Note: This is an experimental add-on, only for Windows at this time. So you will need to login to the Firefox Add-ons site to grab it or click the check mark box next to Let me install this experimental add-on.
This is a great Firefox add-on if you spend a lot of time navigating through the pages you just visited. Pickup the History Tree add-on for Firefox and check out a different view of the pages you have visited.
