Download Pop-Up Box gone

[3pointers]

I must have clicked on something somewhere to change things and can't figure out what I did.

System Info:

OS X 10.5.7
MacBook Pro 4.1
Firefox 3.0.10
App: Download Status Bar

Before screwing things up, when I clicked on a file to download, a pop-up box would appear asking me if I wanted to open the file and unzip it or save it.

Now, when I click on a file to download, it automatically starts downloading and does not unzip it.

Does anyone know what I screwed up?

Thanks.

Try

Firefox > Preferences > Main > then play with the downloads tick box to see if that fixes it

Or, if that doesn't work

Firefox > Preferences > Applications and see what you've told Firefox to do with certain file extensions

Thanks, I found the problem under Firefox>Preferences>Applications.
