Is ` new Object() ` needed here? Maybe this is nit-picky, but I'd prefer using
```js  
chrome.tabs.create({'url': 'https://sendmail4911.herokuapp.com/extensionauth'}); 
``` 
[(I cite Crockford to my side!)](http://yuiblog.com/blog/2006/11/13/javascript-we-hardly-new-ya/) 

Also, what would be really could here would be 
```js
chrome.tabs.create(someoption.fromsomewhere.authurl) 
```
that'd be nice
