Same Firefox downloader. You choose the schedule.
This is a very simple extension for Firefox to allow you to schedule downloads to start at a later time. The usual use-case is for people who have a plan with their internet service provider for a limited amount of monthly usage but with the exception of an off-peak time. This extension can allow you to setup those files for the off peak time and enjoy some good sleep without worrying about exceeding your monthly usage.
To install visit the Mozilla addons page at http://addons.mozilla.org/firefox/addon/58271/. It has now been updated for Firefox 26.
It is very simple to use once installed:
Right click a link a choose 'Schedule Link As...' rather than 'Save Link As...':
Which will bring up the file chooser:
Followed by this dialog to enter the date/time:
Each of these scheduled downloads can then be view, changed and cancelled through here:
