Changes for add-on and Mozilla developers

  • The interface nsIDOMWindowUtils now supports the Boolean attribute audioMuted and audioVolume, a float in the range [0.0 , 1.0], allowing to control the sound produced by a window (that is any tab or iframe). There is no UI for this, but is available to add-ons. (Firefox bug 923247)
