Meh... I personaly don't use it for day to day browsing .. I prefer midori or epiphany for that... Not that it's "atrociously" slow or anything.. but when there is faster alternatives we'll definitely go for that.

But just for the purpose of what you want you could take 10-15 mins to go to the page, download your video and close iceweasel...

It'll take you a little LONGER than doing it on a desktop for sure.. however I don't know how long it takes you to transfer from the DT to the NIT .. so you may just break even.

Course I haven't actually -tried- downloadhelper since I got flash to work in debian.. So I will try it tonight and let you know if it's worth it . I just know it's "theoretically" possible..
