Since no one mentioned it, I just wanted to make sure this thread is

of the Network Information API [1], which provides
navigator.connection.bandwidth
It's been recently implemented (to some degree) in both Mozilla [2] and
Webkit [3].
As far as I can tell, the Mozilla implementation always returns Infinity
for .bandwidth.
This is not true. There is an implementation for Firefox Android which
is based on the connection type.
Ah, indeed. I had missed that codepath.
If I'm reading the right code now, that looks like it returns a constant
value for each connection type (e.g. if you're connected via Ethernet or
Wifi it returns 20; if you're connected via EDGE it returns 0.2, etc).
This suggests that the API is extremely silly; although one could
presumably claim that "an estimate" allows one to return anything, I
don't see how returning "20" if the server is feeding you 1 byte/second
can be helpful to anyone. If no one plans to implement this as a loose
proxy for "type of connection" the spec shouldn't pretend to do more
than that.
Can you point me to the discussion of usecases that led to this design?
