Is jdownloader.org Safe?

Directly after downloading this, firefox asked me if I wanted to install two addons. Very suspicious. It also changed my homepage, though I don't know how since it was supposedly protected. I'm scanning my username/appdata now with as many clients as I have. Hopefully I can spot the offending folder. I'm going to sandbox it and play this one very carefully. I am not in the mood to do a disc restore right now. Update: So I go to update it and it starts downloading all sorts of crap that it shouldn't. Why is it downloading crap for internet explorer and firefox? Obviously, I aborted the update and uninstalled it. This program is BAD NEWS! You can expect ads and privacy invasion if you install this. I'm done with this investigation; you have been warned.
