How do I make Firefox auto-refresh on file change?

Question

Does anyone know of an extension for Firefox, or a script or some other mechanism, that can monitor one or more local files. Firefox would auto-refresh or otherwise update i

Have a look at FileWatcher extension: https://addons.mozilla.org/en-US/firefox/addon/filewatcher/

• it's a WebExtension, so it works with the latest Firefox
• it has a native app (to be installed locally) that monitors watched files for changes using native OS calls (no polling!) and notifies the WebExtension to let it reload the web page
• reload is driven by rules: a rule contains the page URL (with regular expression support) and its included/excluded local source files
• open source: https://github.com/coolsoft-ita/filewatcher
