title: Can't load page while dev-console is open
body: <p>Today i encountered a problem using chrome.
  Everything worked fine yesterday, no new plugins or anything installed, chrome is still the same version.</p>
  
  <p>Whenever I have the dev-tools open and try to reload the page, chrome tells me, it can't get a connection. The console also drops this warning:</p>
  
  <pre><code>/deep/ combinator is deprecated. See https://www.chromestatus.com/features/6750456638341120 for more details.
  </code></pre>
  
  <p>I already searched for this, but couldn't find any help. Hope you can help me with this problem. Never had any problems like this before.</p>
