This is the new Mozilla Sunbird 0.8, Portable Edition, the popular standalone calendaring and task management application built on the same technology as the Firefox web browser.
It is fast, easy to use, customizable and makes keeping your calendar and tasks up-to-date a breeze so you can take your birthday reminders and to do lists with you wherever you go.
In addition, you can easily synchronize with your online Google Calendar.
You can place it on your USB flash drive, iPod or portable hard drive and use it on any computer, without leaving any personal information behind.
Mozilla Sunbird is Open Source, meaning this is the full version, royalty-free and containing no Spyware or Adware.
In addition, if you already use the popular e-mail client Thunderbird, you can get Sunbird packaged as the Lightning extension.
