Body
You should only have to register for the event once, and you should receive it every time a browser tab fires it. Your code should work just fine, provided you are waiting for the XUL window to fire its <code>load</code> event before adding an event listener to the gBrowser element. If you are adding an event listener before that, gBrowser is not yet initialized, and the behavior is undefined. Here is an example: <pre><code>window.addEventListener('load', function () { gBrowser.addEventListener('DOMContentLoaded', function () { // stuff that happens for each web page load goes here }, false); }, false); </code></pre> Note that in practice I can only be sure this works with Firefox 3.5 and up. I wrote an extension (internal to my company) that does this sort of thing reliably for Firefox 1.5 through 3.5, but it is unfortunately a bit more complicated (and fortunately) much more robust than the solution above. If you need support for more than Firefox 3.5+, let me know and I'll provide more info.

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.
