SABnzbd Forums

I'm searching for tools/addon for firefox or external client for manual feeding sabnzbd with nzb's but with category support something like sabdrop for opera, that I can select which link would go into the which category through the context menu, same like with sabdrop.
The most important is that it support NZBS.org indexer.

Just to mention nzbdstatus 1.5x or 2.0x versions doesn't do what I need.
