Comment:

 I just spent a few minutes learning a little bit about EMET, but there is
 a lot to learn.  The following issue report (which I found via an Internet
 search) might be helpful:

 https://trac.videolan.org/vlc/ticket/10583

 Some thoughts after reading that ticket:

 - It might take a lot of effort for Tor developers to determine why EMET
 detects a problem.  It might be a real problem, or just an incompatibility
 between Tor Browser and EMET's checks.

 - It sounds like VLC is also built with MinGW-w64, which probably explains
 why Mozilla's Firefox is not affected by this problem.

 - Since the Tor Browser executable has the same name as Firefox's
 (firefox.exe), I wonder if the rules that Microsoft applies to Firefox are
 also applied to Tor Browser (not necessarily a good thing since we cross
 compile and Mozilla uses MSVC).  Of course I do not know if Microsoft has
 special rules for Firefox, but it sounds like they do for VLC so it is
 certainly possible.
