It would be cool if we could have a notification sent to your phone via the firefox app whenever your desktop finishes a downlod. To minimize annoyances, add a slider in the settings for the minumum requirement for a notification to be sent, or you can make it so where certain websites can be added to a whitelist which allows these notifications. This would help with downloading files from a sources like archive.org which has a huge download time.
Let me know your opinions to this
