View your history as a tree
Tristory not only keeps track of the webpages you visit, but the order in which you visit them. This allows it to display your history in a new and exciting way: in the form of a tree. With the interactive interface, you can easily read, and search your web browsing history
This extension ONLY stores your history locally.
This project is open-source (and still a work in progress). Feel free to check out the code on GitHub.
