Functions defined jstypedarray.h are mostly not meant to be public. We should get rid of every call that uses them directly and reimplement these calls through jsapi.h . For reference, here is the list of culprits at the time of this writing: /dom/workers/FileReaderSync.cpp /dom/workers/XMLHttpRequestPrivate.cpp /content/html/content/src/nsHTMLAudioElement.cpp /content/events/src/nsDOMNotifyAudioAvailableEvent.cpp /content/canvas/src/CustomQS_WebGL.h /content/canvas/src/WebGLContextValidate.cpp /content/canvas/src/WebGLContextGL.cpp /content/base/src/nsDOMFileReader.cpp /content/base/src/nsDOMBlobBuilder.cpp /content/base/src/nsXMLHttpRequest.cpp

And /js/xpconnect/src/XPCConvert.cpp

/dom/telephony/Radio.cpp

evilpie has a patch for almost all of these in bug 711843.
