Lightning brings the Sunbird calendar to the popular email client, Mozilla Thunderbird. Since it's an extension, Lightning is tightly integrated with Thunderbird, allowing it to easily perform email-related calendaring tasks.

Lightning is a popular calendaring, scheduling and task management extension. Mozilla Sunbird® is a cross-platform application that brings Mozilla-style ease-of-use to your calendar.

* The Mozilla Foundation may use any directed donation for other purposes if the Board of Directors is unable to find suitable activities to fund for a project, if a project becomes inactive or otherwise becomes ineligible to receive funds.
