you have number of approaches. old-school way manipulate nsifile , nsifileoutputstream directly, although can't write null bytes way. can create nsistringinputstream string , write output stream, or can utilize nsiasyncstreamcopier re-create asynchronously. fileutils.jsm , netutil.jsm exist seek create easier you.

however, if targetting new plenty versions of firefox, can ignore , utilize os.file api instead.
