+        <ul>
+          <li>
+            Disable <code>content -> enable-pdfjs</code> and reload the page.
+            You will need to download the pdf-file and open it with an external
+            tool instead.
+          </li>
+
+          <li>
+            If you have installed a packaged version of qutebrowser, make sure
+            the required packages for pdf.js are also installed.
+          </li>
+
+          <li>
+            If you have installed a pdf.js package and qutebrowser still can't
+            find it, please send us a report with your system and the package
+            name, so we can add it to the list of supported packages.
+          </li>
+
+          <li>
+            If you're running a self-built version or the source version, make
+            sure you have pdf.js in <code>qutebrowser/3rdparty/pdfjs</code>.
+            You can use the <code>scripts/dev/update_3rdparty.py</code> script
+            to download the latest version.
+          </li>
+        </ul>
+
+        <p>
+          If none of these fixes work for you, please send us a bug report so
+          we can fix the issue.
