Your example worked fine for me, and returned a list of search results from HN for me with the words 'foo' 'bar' and 'baz'.

Firefox 25 on OSX gives me:

  The address wasn't understood

  Firefox doesn't know how to open this address, because
  the protocol (site) isn't associated with any program.

  You might need to install other software to open this
  address.

Firefox 21 on Ubuntu was giving me the same thing, I don't think I've tried it on Firefox 25 on my Ubuntu install.
