RSS feed reading in Firefox

For some reason, searching is a big deal for me, second only to having the right set of keyboard shortcuts.

A quick 20 minute spin of all 3 of your finalists:
- Digest seems unable to search across all feeds
- Bamboo gave me results from feeds I hadn't even subscribed to, using Google!
- Newsfox doesn't even have search (well it has search folders, but they're pretty tedious and too much work for ad hoc searches)
