Request URL:chrome-extension://cahedbegdkagmcjfolhdlechbkeaieki/
Request Headers CAUTION: Provisional headers are shown.
User-Agent:Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko)
   **Chrome/32.0.1700.107** Safari/537.36

It is send from one of my 50 or so extensions.

How can I identify the extension sending the failed request and remove it?
