Computer Thingy

OK, this may be lame (and if the solution turns out to be simple, then it will be very lame), but I need help fixing a setting on my computer.

When doing things like clicking on torrent links, I window would pop up that would give me the option of opening the link with a program or saving it. Well, something happened and now I can only save things, it no longer gives me the option window, and I don't know how to change it back. There doesn't seem to be anything in the internet options that allows me to switch it back to the way it was.

Anyone got any idea how I can fix this? ._. In case it matters, my OS is XP and I use Firefox.
