Recovering Deleted Profile/Bookmarks

more options

I kept getting the "A copy of Firefox is already open" error, so I deleted one of the two profiles that I found. Apparently I chose the wrong one, and now all of my bookmarks are gone. I DID click something that said NOT to remove all my information (bookmarks, etc) so there must be a way to get it back, but how? I really only care about the bookmarks.

Also might be important to mention that I'm on Mac, not Windows.
