Pocket was a too strong integration probably. Offline browsing on mobile phones is still a missing feature, and pocket doesn't solve it well. Firefox could have added the necessary features for a great pocket plugin (and its competitors) instead of just integrating with it (and buying it). Blender is a much more successful example (and there was another open source project here on HN with $300k income where companies could pay for features to be implemented, but still not company specific).
