firefox does not prevent standby when downloading files. currently i have the system set to go into standby after 10 minutes of inactivity. the only time a download completes is when a file is a certain size and it is downloading at a certain speed. the download must and will only complete before the inactivity timer goes into effect as long as the parameters that i explained in the previous sentence fall into place. an example would be a file size of 100 megabytes with a transfer speed of 200 kilobytes per second this equals a download that will complete in 8 minutes and 32 seconds. that is 1 minute and 28 seconds before the system goes into standby,a download that has completed before the pc has sent itself into standby.  example: a file with the size of 100 megabytes transferring at a speed of 100 kilobytes per second equals a download that will complete in 17 minutes and 4 seconds. that is 7 minutes and 4 seconds after i have set the pc to go into standby,a download that has not finished before the pc has sent itself into standby. which means that you must set your computer inactivity timer to go into standby after 20 minutes or longer. this is not safe because download speeds can drop while downloading a file. 

Reproducible: Always

Steps to Reproduce:
1.set the computer to go into standby after 10 minutes of inactivity
2.download a file with the size of 100 megabytes at a speed of 100 kilobytes per second or slower
3.
Actual Results:  
the laptop put itself to sleep even though the download did not complete

Expected Results:  
firefox should have kept the pc from going into standby while downloading the file. after the download has completed the system should then send itself into standby after whatever amount of time the inactivity timer has been set by the user

file sizes vary. download speeds vary before and during a download. a download may advertise a speed of 400 kilobytes per second before it begins and dramatically drop during. even if a download maintains a constant speed during transfer it may not be enough time to complete the download before standby is initiated. also each computers standby settings are different,meaning that my standby settings and examples given are not identical to every pc.
