<p>If you are using Microsoft Edge or Firefox browser you might have noticed that Youtube loads much slower than in Google Chrome.</p>
<p>At first you might think it&#8217;s the browser&#8217;s fault, but actually, it is not. The reason for this slowness lies in the new YouTube&#8217;s <strong>Polymer</strong> redesign which depends on the deprecated Shadow Document Object Model (DOM) 0 API which is only implemented in Google Chrome.</p>
<p>Ironically, YouTube still hasn&#8217;t been updated with the new refreshed Polymer. And while Google is still using outdated API&#8217;s, the rest of the web browsers have adopted new/modern standards. Considering this is encoded in YouTube&#8217;s page coding it is causing issues for modern browsers.</p>
<p>Here&#8217;s how to fix this problem for Firefox and Edge browsers:</p>
<p><strong>Firefox</strong></p>
<p>Please download and install <a href="https://addons.mozilla.org/en-US/firefox/addon/youtube-classic/">YouTube Classic add-on</a> that will fix this problem.</p>
<p><strong>Microsoft Edge</strong></p>
<p>Open any video on YouTube.com website.<br />
From the Edge Menu, click on the <strong>Developer Tools</strong>.<br />
Select <strong>Debugger</strong><br />
Expand <strong>Cookies</strong> and Select <strong>Watch</strong><br />
Replace <strong>PREF</strong> value with: <strong>al=en&;f5=30030&;f6=8</strong></p>

<p>Open YouTube again and Videos should load faster now.<br />
Please have in mind that if you delete the cookie you&#8217;ll have to repeat the process. With this action, you will revert YouTube to pre-Polymer design so it will look different.</p>
<p>If you don&#8217;t like offering solutions you can still use <a href="https://www.microsoft.com/en-us/p/mytube/9wzdncrcwf3l">MyTube!</a> desktop app that will provide you with the best YouTube experience on a Windows machine. Good things don&#8217;t come for free, therefore <a href="https://www.microsoft.com/en-us/p/mytube/9wzdncrcwf3l">myTube!</a> costs only $0.99 but also contains in-app purchases.</p>
<p>Or you can just wait for Google to update the page coding for YouTube.</p>
