    <p>From reading examples, this seems like it should be quite easy. Here's my code:</p> <pre><code>rhkTest = { onPageLoad: function(event) { var doc = event.originalTarget; var wnd = doc.defaultView; var loader = Components.classes["@mozilla.org/moz/jssubscript-loader;1"] .getService(Components.interfaces.mozIJSSubScriptLoader); loader.loadSubScript("chrome://rhkoshi-extension/content/testfoo.js", wnd); alert('typeof(wnd) = ' + typeof(wnd)); alert('typeof(wnd.window.rhk_test1) = ' + typeof(wnd.window.rhk_test1)); alert('typeof(wnd.window.rhk_test2) = ' + typeof(wnd.window.rhk_test2)); alert('typeof(wnd.window.rhk_test3) = ' + typeof(wnd.window.rhk_test3)); alert('typeof(wnd.rhk_test1) = ' + typeof(wnd.rhk_test1)); alert('typeof(wnd.rhk_test2) = ' + typeof(wnd.rhk_test2)); alert('typeof(wnd.rhk_test3) = ' + typeof(wnd.rhk_test3)); alert('typeof(rhk_test1) = ' + typeof(rhk_test1)); alert('typeof(rhk_test2) = ' + typeof(rhk_test2)); alert('typeof(rhk_test3) = ' + typeof(rhk_test3)); alert('typeof(this.rhk_test1) = ' + typeof(this.rhk_test1)); alert('typeof(this.rhk_test2) = ' + typeof(this.rhk_test2)); alert('typeof(this.rhk_test3) = ' + typeof(this.rhk_test3)); alert('typeof(window.rhk_test1) = ' + typeof(window.rhk_test1)); alert('typeof(window.rhk_test2) = ' + typeof(window.rhk_test2)); alert('typeof(window.rhk_test3) = ' + typeof(window.rhk_test3)); }, onLoad: function(event) { var appcontent = document.getElementById("appcontent"); if (appcontent) { appcontent.addEventListener("DOMContentLoaded", rhkTest.onPageLoad, true); } }, }; window.addEventListener("load", function(e) { rhkTest.onLoad(e); }, false); </code></pre> <p>where testfoo.js contains:</p> <pre><code>window.rhk_test1 = 'testval1'; rhk_test2 = 'testval2'; var rhk_test3 = 'testval3'; window.alert('Running testfoo.js'); </code></pre> <p>I get the alert "Running testfoo.js", so the file is found and executed. I also get an alert noting that wnd is an "object" (as expected -- it's initialized elsewhere). However, all the other alerts show "undefined" for the various typeof() calls. Naturally, I don't expect <em>all</em> of these to have values, but I was hoping that at least <em>one</em> of them might show something.</p> <p>What happened to my values? Aren't they supposed to be in properties of wnd?</p> <p>I'm running Firefox 19.0 on Windows 7 (if that matters).</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.

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