Sunbird® is a cross-platform application that brings Mozilla-style ease-of-use to your calendar. The Lightning extension adds a fully integrated calendar to Mozilla Thunderbird.
Which is right for me?
You may prefer Lightning if...
- you send or receive meeting invitations via email
- you already use Mozilla Thunderbird for email
- you customize your applications with add-ons (such as extensions or themes)
You may prefer Sunbird if...
- you prefer your calendar to be separate from your email client
- you don't currently use Mozilla Thunderbird for your email
- you don't like adding add-ons (such as extensions or themes) to your applications
