 Replying to [comment:1 mcs]:
 > This is probably also a bug in Firefox although I did not find a bug
 report at bugzilla.mozilla.org. There is a "Connecting to the update
 server…" message that is shown initially and presumably it is not supposed
 to be changed until the download size is known.

 > Are you able to reproduce this reliably? On what OS? I have seen this in
 the past (but not recently) and I was not able to reproduce it with a
 6.0.4 to 6.0.5 update. From a quick read of the code, I would say it tries
 to avoid division by zero, but there are enough layers of code that I am
 not 100% sure (divide by zero does seem like the most likely root cause of
 this).

 I am on OS X. I am also on networks where latency is high (~100-500ms), so
 that could be a factor.

 I'll see if I can replicate the issue with Tor Browser 6.0.4 -> 6.0.5.
