Use JavaScript Modules
Instead of the <script> tag in overlays JavaScript that is loaded via the script tag can slow window load. If your script is not needed as part of window setup, and doesn't need to be loaded for each individual window, then load it on-demand as a module.
Instead of JS XPCOM services JavaScript code modules are singletons, are fastloaded, and don't require XPCOM like a full-blown JS XPCOM service does.
