title: Chrome Extension in incognito mode
body: <p>I have an extension for Chrome that makes ajax request to my site. The site uses sessions.
  So, in response of the ajax request to the site, the Set-Cookie header is returned with some session identifier and a this entry appears in the cookie section of the extension DevPanel (of the backgroud page).
  But, session id in the DevPanel browser for the site is a completely different.
  Extension is allowed for incognito mode.</p>
  
  <p>In normal mode, the cookies are identical in the DevPanels of the extension and the browser.
  I understand that cookies for normal and incognito modes should be different, but why are these values ​​different for the extension allowed for incognito mode?</p>
  
  <p>Am I right and extensions allowed for incognito mode, work in normal mode?</p>
