This happened with a 232MB file, and has been reproduced. Reproducible: Always Steps to Reproduce: 1.Start a download from HTTP (I assume it is the same for FTP downloads) 2.Pause the download 3.Unplug or disconnect the current LAN connection 4.Enable a seperate local area connection (In this case a wireless NIC) 5.Attempt to resume the download. Actual Results: The download is marked as completed , yet the entire file has not been downloaded. Expected Results: The download should resume as normal, barring the total unavailability of any LAN connection. Default theme. No additional extensions installed in Firefox. Going from a bound media LAN connection to an unbound (wireless) LAN connection.
