How to crate a plugin which will change background color of specific page say facebook.com on load of page?

I checked samples provided by Google but not able to figure out how to execute script automatically as soon as a user open specific page ( e.g. facebook.com ) in new window or tab.

  • What have you tried on coding ? Sounds like you want to make something like userscripts. – Raptor Oct 10 '13 at 06:07

In your manifest add:

"content_scripts":[{
    "matches": ["http://www.pageYouWantToModify.com/"],
    "css": ["css.css"],
    "js": ["javasript.js"]
}],

The css.css and javascript.js file will run when you open "http://www.pageYouWantToModify.com/"
