Easier backtracking in Firefox 3 with History Submenus

I don't refer to my browsing history all that often, but there are times when I need to go back and find a particular something that I just can't remember by name. Firefox's default Today/Yesterday/every day this week setup isn't really the tidiest way to go back three or four days, and it's hard to search when you can't recall what to search for.

History Submenus makes the task a bit easier by providing today and the last seven days (by default) as separate menu choices. Its options allow you to specify the number of items to display, including individual entries at the top of the history menu, days to include as submenus, and recently closed tabs.

The add-on also provides quick access restoring tabs and windows from your previous browsing session. Though it's listed as working with Firefox 3-3.1b3, it works fine in more recent (less stable) builds as well.
