How can I finish downloads on Rapidshare Free? - rapidshare large and in charge

When I try to not stop files from Rapidshare freeze after a random time and again. For files that are larger than 10-20 megabytes, which is rarely a complete download and usually has to make several attempts to download.

I have a relatively fast internet and I use Firefox 3.5.3.

All ideas) (apart from more premium, how to quit you download first to my experiment?
