    <p>In case of XUL/Firefox, what you need is the nsIIOService interface, which you can get like this:</p> <pre><code>var mIOS = Components.classes["@mozilla.org/network/io-service;1"]. getService(Components.interfaces.nsIIOService); </code></pre> <p>Then you need to create a channel, and open an asynchronous link:</p> <pre><code>var channel = mIOS.newChannel(urlToOpen, 0, null); channel.asyncOpen(new StreamListener(), channel); </code></pre> <p>The key here is the <code>StreamListener</code> object:</p> <pre><code>var StreamListener = function() { return { QueryInterface: function(aIID) { if (aIID.equals(Components.interfaces.nsIStreamListener) || aIID.equals(Components.interfaces.nsISupportsWeakReference) || aIID.equals(Components.interfaces.nsISupports)) return this; throw Components.results.NS_NOINTERFACE; onStartRequest: function(aRequest, aContext) { return 0; }, onStopRequest: function(aRequest, aChannel /* aContext */, aStatusCode) { return 9; }, onDataAvailable: function(aRequest, aContext, aStream, aOffset, aCount) { return 0; } }; } </code></pre> <p>You have to fill in the details in the <code>onStartRequest</code>, <code>onStopRequest</code>, <code>onDataAvailable</code> functions, but that should be enough to get you going. You can have a look at how I used this interface in my Firefox extension (it is called IdentFavIcon, and it can be found on the mozilla add-ons site).</p> <p>The part which I'm uncertain about is how you can trigger this page request from time to time, <code>set_timeout()</code> should probably work, though.</p> <p><strong>Edit:</strong></p> <ol> <li>See example <a href="https://developer.mozilla.org/en/Code_snippets/Downloading_Files" rel="nofollow noreferrer">here</a> (see section <em>Downloading Images</em>) for an example on how to collect downloaded data into a single variable; and</li> <li>See <a href="https://developer.mozilla.org/en/Code_snippets/HTML_to_DOM" rel="nofollow noreferrer">this page</a> on how to convert an HTML source into a DOM tree.</li> </ol> <p>HTH.</p>

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
