Comment:

 The problem is that we don't check whether a content or a chrome script is
 trying to extract data. As we are extracting the script file anyway we
 probably could either check for a scheme indicating a chrome script (like
 (resource://) or maybe there is even a better method giving back a yes/no
 if asked whether that is a content script or not. I have not looked closer
 at it yet.

 The Inspector raises the issue in ESR 31 (and not earlier) as it had not
 been using canvas extraction in ESR 24.
