Are you absolutely sure ff_show is correct slug? I have suspicions about that underscore…
category is not valid query argument at all, it is probably simply discarded.
Had you tried this query with id instead of slug? cat argument.
Edit.
Wait, you are trying to query custom taxonomy? Category arguments have no relation to it at all.
Try frontpage_categories => ff_show (quick guess, don’t remember specifics of querying custom stuff. again – not my area).
Yeah, found it at last Custom Taxonomies > Querying by Taxonomy
