<h4 id="activated-scripts">Activated scripts</h4>
<p>Activate either local (bookmarklets) or remote js to execute the code on the similar sites with option &quot;Activate user script&quot;.</p>
<p>Since activated scripts use internal mechanism of <a href="../links/index.html">&quot;i:0m&quot; urls</a>, the script itself cannot have <span style="color:red">'H', '?' or '/'</span> as its very first character.</p>
<h4 id="allow-remote-js-on-csp-content-security-policy-sites">Allow remote js on CSP (Content Security Policy) sites</h4>
<p>All remote js (default.rjs) are allowed to execute on CSP sites. Local js files without remote resource access work fine when under the folder &quot;bookmarklet&quot;, others needs to be refered in default.rjs as http urls such as &quot;https://local/...&quot; (<a href="../html5/index.html">html5</a> or <a href="../offlinecache/index.html">offline cache</a>) .</p>
