Firefox also allows to search without bringing up the search bar first by setting "accessibility.typeaheadfind" in "about:config" to true. Reducing the timeout for the search bar to disappear after the last keypress is very useful as well. This is hidden behind "accessibility.typeaheadfind.timeout". Caveat: is messes with pages that use normal letters as keyboard inputs, like WASD as movement keys. One might need to disable it temporarily if that happens.
