Opensource rocks.

i've known about it for over a year and believe me when i say that the reason i use firefox! people have actually dumped their professional download managers which they paid for because of this baby.To get maximum download speeds be sure to increase the number of chunks to 10 in the downthemall extensions options.There, now you can download the internet in one day!
