One of the problems I have downloading large files like episodes to shows and stuff is that it takes way too long and I can never actually finish the download.

My internet connection's kinda crappy and I can't keep up a connection for more than maybe 15 minutes. Sometimes I might try to download a file that takes half an hour to download and then my connection will go out for just a quick second. For some reason Firefox treats interrupted downloads as completed downloads but you really just end up with a corrupt file.

Is there any kind of download manager for Firefox or anything that will pause a download and save its place if the download is interrupted by a dropped connection and resume it once the connection comes back up? The best I can do right now is Star Downloaer which if interrupted, gives the connection 10 seconds to come back up before it drops the task completely. Is there anything else?

Yes

But i forgot the name.Go to download.com
Internet tools.You'll find one with a resume option you can do even days later.
I'll shake my brain overnight.

Download Accelerator.
