I have several applications I use regularly on multiple macs. For specific file types, Firefox 4 will only give me the option to save the file. It does not allow me to select an app to use, and, the file type is not listed in the Content Type list on the Applications tab in Preferences.

In particular, I have XLS associated with Excel, but XLSX is not listed, so all I can ever do is save it, then open it.

Another case, on one mac, PDF is associated with Preview, but it is not listed on the other, so again, all I can do is save it. It doesn't allow me the option to change actions.

There must be a place to change the default behavior for unknown file types, isn't there?
