Answer 1

Why are you trying to pass the tabUrl variable to chrome.tabs.create ? You can call the tab.url information in the chrome.tabs.create method.

background.js

chrome.browserAction.onClicked.addListener(function(tab) {
    chrome.tabs.create({
        url: "http://www.google.com/search?q=" + tab.url  //Changed the URL for testing
    });
});
