How to I change the settings for opening pdf files on my Mac?

When I open pdf files, the computer automatically uses Preview and saves the documents to my desktop. However, I'd rather use Acrobat--- and I very much don't want the documents to clutter my desktop anymore! I have downloaded Acrobat, but right now it doesn't even come up as an option when the ';open file with...'; box pops up.

Finally! Someone smart enough to not have windows!



First, if you are using Firefox, go to Edit -%26gt; Preferences -%26gt; Click on the 'Main' tab. Under the downloads section, it should have 2 checkboxes. One says ';Save Files To Desktop'; another says ';Always ask me where to save Files'; Obviously, you want the second box.
