Simple forwarding using Google Chrome webRequest API
Your url matching pattern isn't correct. You simply need to add a trailing slash:
{urls: ['https://www.google.com/']}
Alternatively, you could use: '*://www.google.com/' to match all protocols, '*://www.google.com/*' to match beyond just the domain, and '*://*.google.com/*' to match all subdomains, protocols and paths, etc.
