Did you know that when you type special characters into Firefox's location bar (aka: url bar, awesome bar) it filters/focuses the location bar's search results. For example, enter "%" to show only results from currently open tabs, or "*" for just your bookmarks, or "^" for just your history, etc.
This super simple add-on just provides a toolbar button that displays a panel to remind you what the characters are and what they do. Here they are:
^ Browsing history
* Bookmarks
+ Pages you've tagged
% Currently open tabs
~ Pages you've typed
# Page titles
@ Web addresses (URLs)
They can be entered before or after search terms. Learn more about them here:
