Just been downloading the VS2010 Release Candidate(4 files) and got to within 5mins of completing it when I lost my connection. I thought Firefox would just restart the download from where it left off, but no, its starting from the beginning again. Didnt restarting downloads used to be a feature of Firefox? Is it still there? Where do I turn it on?

I've never noticed Firefox picking up where it left off when a download failed. It may have a thing it calls a download manager, but it's not the same kind of thing as a Getright or Gozilla-type program that resumes downloads.
