That app is moving to another site but you can still get downloads, I believe, at http://www.krasu.ru/soft/chuchelo/
I installed my distro's version for some reason I've now forgotten.
EDIT: BTW, I have looked up Flashgot. It isn't a download manager; it's a plugin to let you use other download managers with Firefox. I'm hoping it will force Firefox to use d4x on my system. You may also want to look at this: http://en.wikipedia.org/wiki/Compari...nload_managers
