Do browsers today really not hide javascript?
<p>(This is not a duplicate of <a href="http://stackoverflow.com/questions/822872/do-web-sites-really-need-to-cater-for-browsers-that-dont-have-javascript-enabled">this question</a>).</p>

<p>Are there any browsers today that, if they do not support javascript tags, fail to hide it? E.g., Firefox with adblock will not run javascript, but will not display it directly to the user.</p>

<p>This <a href="http://www.w3schools.com/js/js_howto.asp" rel="nofollow">w3school tutorial</a> claims you should hide javascript tags with comments, like this:</p>

<pre><code>&lt;script type="text/javascript"&gt;
&lt;!--
document.getElementById("demo").innerHTML=Date();
//--&gt;
&lt;/script&gt;
</code></pre>

<p>otherwise these browsers will display the JS code. This seems a bit irrelevant today ... is it?</p>
