 Actually, a) may be the problem.  Here is the implementation of XXX:
 https://gitweb.torproject.org/tor-browser.git/blob/refs/heads/tor-
 browser-31.2.0esr-4.x-1:/toolkit/mozapps/update/updater/updater.cpp#l736

 The "err: 75" that was logged indicates errno 75 after a call to lstat(),
 which is EOVERFLOW.  On your 32-bit system, I think lstat() will fail like
 this on any files larger than 2GB.  I wonder if Mozilla has an open bug
 for this problem....
