Session History Tree augments Firefox's back/forward menu, allowing you to revisit pages and their associated session histories even after you have navigated back and gone to other pages.
The normal linear list is kept, but for every page that has one or more "siblings" in the tree, a submenu is available. Look inside to see all of the pages visited from the previous page. And if any pages were visited from those, they are displayed in further submenus.
