<p>As Andrew stated your first problem is probably that your doing it from file://. Try doing it from an extension.<br> After that you'll probably like to know that from Chrome 19 you can ask for the response from an xhr to be a blob.<br> Then for saving the file your better off using something like <a href="https://github.com/eligrey/FileSaver.js/" rel="nofollow noreferrer" title="FileSaver.js">FileSaver.js</a> to save the file. The iframe way works but you end up with an awful file name.<br> Here's an example to get you going.... </p> <p><strong>manifest.json</strong> </p> <pre><code>{ "name": "Download a file and click to save.", "version": "1.0", "permissions": [ "tabs", "<all_urls>" ], "browser_action": { "default_title": "Download a file and click to save.", "default_icon": "icon.png", "default_popup": "popup.html" }, "content_security_policy": "script-src 'self' https://raw.github.com/; object-src 'self'", "manifest_version" : 2 } </code></pre> <p><strong>popup.html</strong> </p> <pre><code><!doctype html> <html> <head>  <script src="https://raw.github.com/eligrey/FileSaver.js/master/FileSaver.min.js"></script>  <script src="https://raw.github.com/allmarkedup/jQuery-URL-Parser/no-jquery/purl.js"></script> <script src="popup.js"></script> </head> <body> <div id="message">Getting File.....</div> </body> </html> </code></pre> <p><strong>popup.js</strong> </p> <pre><code>window.URL = window.URL || window.webkitURL; var xhr = new XMLHttpRequest(); xhr.open('GET', 'http://or.cdn.sstatic.net/chat/so.mp3', true); xhr.filename = purl('http://or.cdn.sstatic.net/chat/so.mp3').attr('file'); xhr.responseType = 'blob'; xhr.onload = function(e) { var message = document.querySelector('#message'); message.parentNode.removeChild(message); var link = document.createElement('A'); link.innerText = 'Download File'; link.href = '#'; link.addEventListener('click', saveFile, false); document.body.appendChild(link); }; xhr.onerror = function() { var message = document.querySelector('#message'); message.innerText = 'Error getting file'; this.filename = ''; } xhr.send(); saveFile = function() { saveAs(xhr.response, xhr.filename); // saveAs function is from FileSaver.js } </code></pre>

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
