This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.


The findNext() method of the HTMLIFrameElement highlights the next or previous instance of a search result after a findAll() search has been carried out.

Invoking this method results in a mozbrowserfindchange event firing, which carries details about the search results.

Note: Use of the Browser API requires a privileged app, and browser and/or embed-apps permissions, depending on what you want to do. See Using the Browser API for more details.



Return value



A string indicating the direction in which you want to cycle through the available search results. Available values are forward and backward.


The following functions are taken from our Browser API demo, and cycle through the available search results. See Implementing the search bar for more explanation.

prev.addEventListener('touchend',function() {

next.addEventListener('touchend',function() {
