retrieve a download a file from a "blob" url
<p>A website have a video tag element structured like this:</p>

<pre><code>&lt;video id="playerVideo" width="450px" autoplay="autoplay" height="338px" style="height:100%;width:100%;" class="mejs-rai-e" src="blob:http%3A//www.example.com/d70a74e1-0324-4b9f-bad4-84e3036ad354"&gt;&lt;/video&gt;
</code></pre>

<p>As you can see the src element have an url pre-configured as blob.
Is there a method like a script or a video downloader plug-in to locate the file and download it?</p>
