First Firefox release.

7.8.0 adds Smart Suggestions: a free, read-only scan that finds the senders worth cleaning and says why each one made the list ("431 emails, 97% unread, mostly older than 6 months"). One click cleans a sender through the normal cleanup path, so mail gets tagged first, dry run is honored, and the recovery log still applies.

Suggestions skip anything on your whitelist or protected keyword list. They also skip senders with starred mail and anyone you write back to. Dismissing a suggestion hides it for 90 days, and everything runs and stays on your device.

The top three suggestions are free. Pro ($5, one time) unlocks the full ranked list and bulk apply.
