Looking for a downloader

[firefoxuse]

Is there a GUI method that will download a list of urls that to access them you need to enter login information in a form? Also, I need it to delay x seconds between each download and if possible to search the webpages of the urls in the list so that if it find a link to a pdf/ppt etc file to download them. (I am not comfortable with wget, because it doesn't display progress nor it has a button to pause etc)

thanks!

Not quite sure what you're looking at, but perhaps a web spider?
