Firefox has very handy feature "Search for text when you start typing", with it enabled when you start typing on any page without any input field focused, Firefox calls "Find on page" form (Ctrl + F) and puts inputted text in it.
I would like to have an option for this feature to type in the addressfield instead, because I search to text on page pretty rarely, but I type in the addressfield all the time. It would be handy for me to now use the CTRL + L shortcut all the time, and just start to type.
