This problem has long shown its face in my application.  It seems the 
chrome launcher does not have support for Thunderbird.  The fix is 
tedious and I am yet to get it to work.  Perhaps the devs put this in 
place since they realized this themselves.

Noticed this too.  I chalk it up to a new audio applet, which seems to 
actually be part of the "notifications" if I'm not mistaken.  Likely why 
middle rolls do not work.
