That looks a bit hacky and not easily extensible.

Why not use URL query string parameters instead? `URLSearchParams` might help
making the parsing of those less tedious.

I don't think extensibility matters here. I've implemented this as query
parameters now, not sure this really makes anything better.

   let messageManager = Cc["@mozilla.org/parentprocessmessagemanager;1"]
                          .getService(Ci.nsIProcessScriptLoader)
                          .QueryInterface(Ci.nsIMessageBroadcaster);
   messageManager.loadProcessScript(processScript, true);
 
   onShutdown.add(() => {
     messageManager.broadcastAsyncMessage("AdblockPlus:Shutdown", processScript);
     messageManager.removeDelayedProcessScript(processScript);
