    Option One - Via Firefox

    In Firefox -> Preferences -> General -> Applications:

    You can set "bin" to be "always ask"

    Firefox Preferences

    Option Two - Nuke Your MimeTypes File

    This will reset all of your file associations.

    rm ~/.mozilla/firefox/(unique id).default/mimeTypes.rdf

    You will need to replace (unique id) with whatever yours is named.

    Option Three - Edit Your MimeTypes File

    nano ~/.mozilla/firefox/(unique id).default/mimeTypes.rdf

    Look for the part about "bin" and you can change it to something like this:

      <RDF:Description RDF:about="urn:scheme:bin"
                   NC:alwaysAsk="true">
    <NC:handlerProp RDF:resource="urn:scheme:handler:bin"/>
  </RDF:Description>

    Notice the "alwaysAsk=true" part... this is what will need to be changed in your file
