+<h3 class="section">4.1 LibreJS in action</h3>
+
+<p>After installing the add-on, you will see the LibreJS widget in the
+add-on bar at the bottom of the browser window. After loading a page,
+left-click on the widget to view the deactivated JavaScript code from
+the page (both on page and external) and, if applicable, the scripts
+that were accepted.
+</p>
+<a name="Complaint-Feature"></a>
+<h3 class="section">4.2 Complaint Feature</h3>
+
+<p>It is very important to complain when a site has nonfree JavaScript
+code, especially if it won&rsquo;t work without that code. LibreJS makes it
+easy to complain by heuristically finding where to send the complaint.
+</p>
+<p>When nonfree/nontrivial code is detected in a page, LibreJS attempts to
+find a relevant contact link or email for the website you are
+visiting. In order to do so, it will attempt to visit a few links from
+the current page (for instance, a link labeled &ldquo;contact&rdquo; on the same
+domain as the current page, &hellip;)
+</p>
+<p>LibreJS detects contact pages, email addresses that are likely to be
+owned by the maintainer of the site, Twitter and identi.ca links, and
+phone numbers.
+</p>
+<p>After LibreJS detects any of the above, a &ldquo;Complain&rdquo; tab will appear
+on the right of your web browser. When you click on this tab, a large
+panel will appear with contact information. Ideally, at the top you will
+find the email address of the maintainer, labeled as the &ldquo;Email you
+should use&rdquo;.
+</p>
+<p>When you complain to the website for their nonfree nontrivial
+JavaScript, provide them with the link to the JavaScript Trap essay so
+that they can get more information on what the issue is and how they can
+solve it on their own site.
+</p>
+<p>LibreJS includes a default subject line and body for the complaint email,
+with a link to the JavaScript Trap essay. This can be configured in the
+LibreJS add-on preferences in your web browser.
+</p>
+
+<a name="Options"></a>
+<h3 class="section">4.3 Options</h3>
+
+<dl compact="compact">
+<dt><em>Whitelist</em></dt>
+<dd><p>LibreJS lets you whitelist domain names and subdomains to bypass the
+regular JavaScript check. This might be useful, for example, if you are
+running your own code in a local web server. In order to add a
+whitelisted domain or url, go to Tools &gt;&gt; Add-ons, or press <kbd>Control
++ Shift + A</kbd>. Inside the add-on window, click on <em>Extensions</em>, and in
+the list, where you see LibreJS, click on the <em>Preferences</em> button.
+You will see an input field labeled <em>Whitelist</em>. In the field,
+enter comma-separated domain names. Do not enter the protocol. For
+instance to whitelist all the pages of <a href="http://www.gnu.org">http://www.gnu.org</a> and
+<a href="https://gnu.org">https://gnu.org</a>, enter &lsquo;<samp>gnu.org</samp>&rsquo;. To allow all subdomains from
+gnu.org, enter: &lsquo;<samp>*.gnu.org</samp>&rsquo;. This will match such sites as
+<a href="http://savannah.gnu.org">http://savannah.gnu.org</a> and <a href="http://audio-video.gnu.org">http://audio-video.gnu.org</a>.
+</p>

+<dt><em>Complaint tab</em></dt>
+<dd><p>This specifies whether the complaint tab appears when a site is running
+nonfree JavaScript.

+<dt><em>Display notifications of JavaScript analysis</em></dt>
+<dd><p>This option enables an info bar of realtime JavaScript analysis.
+</p>

+<dt><em>Complaint email subject</em></dt>
+<dd><p>Configure the default subject used in complaint emails.
