title: Disable developer mode extensions pop up chrome54
body: <p>I just upgrade to chrome 54 and iu'm getting this anoy pop up every time i launch chrome
  I tried to use this solution:</p>
  
  <p>run hiew32 demo (in admin mode) and open Chrome.dll
  switch to hex view (Enter key)
  search for ExtensionDeveloperModeWarning (F7)
  press F3 to edit and replace the first letter "E" with any other character
  save (F9).</p>
  
  <p>BUT
   the string ExtensionDeveloperModeWarning is not present anymore in chrome.dll
  So I search and replace any string with the word Warning for larning, and still is not working.</p>
  
  <p>So the problem still exist</p>
