You don't have access to chrome.tabs on an extenal injected site.

You need to pass a message to a background script and call chrome.tabs.create({ url: 'http://www.sethjfreeman.com' }); from there.

Check Message Passing.

It now says: content.js:1 Uncaught TypeError: Cannot read property 'query' of undefined at content.js:1 – Seth J. Freeman Jul 11 '17 at 21:31
Code: chrome.tabs.query({active: true, currentWindow: true}, function(tabs) { chrome.tabs.sendMessage(tabs[0].id, {greeting: "hello"}, function(response) { console.log(response.farewell); }); }); – Seth J. Freeman Jul 11 '17 at 21:32
I read on: one time passing. as i only need it to happen once – Seth J. Freeman Jul 11 '17 at 21:33
