Background

Find As You Type (or Type Ahead Find as it was originally called) allows you to start finding text on the page immediately by simply typing the text you’re trying to find. When typed characters fail to match anything on the page, it can be configured to play an alert sound. This sound can be a built-in sound, a system beep, or an external user-specified file.

Possible values and their effects

default

The default, built-in sound will be played on failed matches. (Once described as “a hoarse dog barking.”) (Default in all products; default in Firefox until 2.0)

beep

The system beep will be played on failed matches. (Default in Firefox 2.0)

(valid path to a WAV file)

The WAV file will be played for the alert sound on failed matches.

(empty string)

No sound will be played (equivalent of setting accessibility.typeaheadfind.enablesound to false).

Caveats

• Setting accessibility.typeaheadfind.enablesound to false will prevent any sound from being played regardless of this preference’s value.
