I'm looking to see if anyone knows of a Chrome extension where you can run saved Javascript code (or run a .js file) for a website after it loads.

So it would be the equivalent to opening up and running some code in the Developer Tools console after the page loads. I'd like something which would automate this process.

    Try Tampermonkey. By default it cannot access filesystem resources, though. Enable it inside the config panel. You still would have to convert your snippets / JS ifles into a specific userscripts format (.user.js), stored "inside Tampermonkey". – knb Jan 11 '19 at 11:43
  • Tampermonkey looks promising! – John Go-Soco Jan 14 '19 at 11:59
