You don't like having your search terms appear on every tab when using Firefox, you say?
Why, Unsearched will clear the search bar for you everytime you navigate to a new tab!
I know what you are thinking: wouldn't it be nice if the search terms magically re-appeared on tabs that you actually used the search box on? Unsearched won't disappoint.
By golly, install this wonderful add-on. It won't even make your Firefox restart. That's a promise!
