You can extend the expiration time on DownloadHelper. Look for it under your Extensions menu and click on Options. Under 'General', click on the 'Behavior' tab. The option to extend the expiration time should be right there; it should say 'Menu entry expiration (sec)' and then to the right of it a box for you to set the time. Default time should be 60 seconds. Set it to whatever you want and you shouldn't have to refresh the page before you've had a chance to download the video again.
