var file = Components.classes["@mozilla.org/filelocal;1"].createInstance(Components.interfaces.nsILocalFile);
file.initWithPath("Pathforfile");

file.create(Components.interfaces.nsIFile.NORMAL_FILE_TYPE, 420 );
var outputStream = Components.classes["@mozilla.org/network/file-output-stream;1"].createInstance( Components.interfaces.nsIFileOutputStream );
outputStream.init( file, 0x04 | 0x08 | 0x20, 420, 0 );
var output="Texttowriteinfile";                                     
var result = outputStream.write( output, output.length );
outputStream.close();

What do you want to do?

HTML5 has a File API. This is the best solution because it allows selection of the file to be wholly under user control.

If you must, you can make your own NPAPI plugin which exposes itself to scripting (aka NPRuntime) and performs native local file operations on behalf of Javascript in the page. Or, in IE, new ActiveXObject("Scripting.FileSystemObject") may yield a FileSystemObject (depending on ActiveX settings). But please don't.
