I had multiple downloads of pdf to do and normally when the download dialog box pops up to ask if I want to open with adobe or save the file, I want to open it with adobe. This time I checked the save and then checked the box to "always do this". Now that I'm done downloading the pdf I want to set it back to open as a default. Do you know where I can do that? I'm not really sure if it's a download feature of firefox or not.

Thanks!
