Hi,
I run into this same problem. I tried installing the add-on mentioned by NoelS but didn't work. Basically, the problem is whenever I try to save something using "Save Link As...", it doesn't show up on Download manager (doesn't even open DL manager), and downloads nothing. Downloading works fine on IE though. Anyone know how to fix this?
Quick history of what's happening: I was watching a Divx movie, and downloading at the same time. Then somehow the PC froze up, so I turned it off by pressing the power button. I tried to reinstall Firefox, even deleted the firefox folder, NOTHING happened. Then I tried to restore my PC from a few days ago, hoping it would fix it, and NOTHING happened as well.
Please HELP!!!!
