Faster Firefox Download Process ?

Lifehacker posted an article letting us know that there was a way to Speed Up the Firefox Download Process by dragging and dropping the download instead of right-clicking and selecting Save As from the menu. I’m a bit puzzled by this article and have my problems accepting their conclusion.

First of all, drag and drop does not work for all websites. If a script handles the download you can’t drag and drop that to the download icon (which you most likely have to add using the customize feature). Second, not all downloads have to be right-clicked and Saved As.

Firefox offers a very distinctive way of selecting an action for file-types. You can choose to save certain file-types, like pdf, doc or avi to the hard drive which means that whenever you left-click them they will be saved to the hard drive instantly.

What do you think, is that a way of speeding up the download process ?
