- Add Lightning 1.0 Beta 1. This version works with Thunderbird 3.0 and
Lightning brings the Sunbird calendar to the popular email client, Mozilla
Thunderbird and the SeaMonkey internet application suite. Since it's an
extension, Lightning is tightly integrated with Thunderbird or SeaMonkey,
allowing it to easily perform email-related calendaring tasks.
