FileReference.load() crashes FireFox

Question

Hi,
I'm using FileReference.load() to upload files to server. Usually the file size is about 50M. It _is_ working fine most of the time. But sometimes it crashes FireFox.
I tried to catch the exception, but I did not see any logging when it crashed.
                try
                    refUploadFile.load();
                catch(error:Error)
                    if (error is IllegalOperationError)
                        trace("error is IllegalOperationError");
                    else if (error is MemoryError)
                        trace("error is MemoryError");
                    throw error;
I'm using Windows XP, FireFox 3.6, Flash Player Debug version 10.0.32.18, Flex Builder 3.0, Flex SDK 3.4
I need to get it fixed. Any idea what I shall do.
Regards,
Haibin

I write a very simple swf with the following code and test it with a selection of 32 files (each file is about 60M). It crashes every time.
var fileRefList:FileReferenceList = new FileReferenceList();
fileRefList.addEventListener(Event.SELECT, selectHandler);
fileRefList.browse();
function selectHandler(event:Event):void
    var file:FileReference;
    var files:FileReferenceList = FileReferenceList(event.target);
    var selectedFileArray:Array = files.fileList;
    for (var i:uint = 0; i < selectedFileArray.length; i++)
        file = FileReference(selectedFileArray[i]);
        file.addEventListener(Event.COMPLETE, completeHandler);
        try
            file.load();
        catch (error:Error)
            trace("Unable to upload files.");
function completeHandler(event:Event):void
    trace("uploaded");
