I have a custom code that I want to run on a specific website through chrome extension. For example I run $("#column2").append('something') in chrome console and it work. I want to do this using an extension so that I do not have to run this manually in console. What should be the background.js file according to this? I'm literally new in chrome extensions, I just want this to be done.
TL;DR: Chrome Extension to run custom string in console.
