Comment (by torleak):

 SnagiIt32.exe was decompiled, and there is indeed a favicon.ico call under
 unclear conditions. This may also explain older Windows NT 6.2 version in
 User-Agent, if this Snagit version itself was relatively old and not
 compiled for Windows 6.3.

 Now, does it mean that an external application can request a target IP
 address from TOR Browser (Firefox), and TOR Browser will divulge IP
 address to it? Is it normal? This doesnt look good.
