Downloading and Installing

Downloading Lightning 1.0 beta2

Before installing, make sure your computer meets the system requirements. Mozilla.org provides Lightning for Windows, Linux and Mac OS X in a variety of languages. Windows users must have Windows XP or later.

IMPORTANT: Install the updated timezones for Windows XP or later. Information on obtaining the updated timezones can be found in Microsoft Knowledge Base article 955839.
Not updating your Windows timezones will result in unreliable and erroneous display and entry of time data! Be sure to do this!

Installing Lightning

Lightning runs as an extension for Mozilla Thunderbird 3.1.x.
Thunderbird 2.0.0.x or 3.0.x is no longer supported. Please use the earlier 1.0b1 (Thunderbird 3.0.x) or 0.9 (Thunderbird 2.0.0.x) release if you still use an earlier version of Thunderbird.

1. Right-click (Control-click on Mac) the download link and choose "Save Link As..." to download and save the .XPI file to your your hard disk
2. In Mozilla Thunderbird, under the "Tools" menu, open the "Add-ons Manager"
3. Click the "Install" button, locate and select the .XPI file you downloaded in step 1, and click "OK"
4. Restart Mozilla Thunderbird

If you are using Seamonkey, please also use the older Lightning 1.0b1. This release doesn't support Seamonkey, but the next release will likely do so again.

Known Issues

This list covers the major known issues with Lightning 1.0 beta2. Please read this list before reporting any new bugs.

• The experimental support for viewing remote calendars offline has various known issues in the area of performance and calendar data display. It does not support the offline editing of events and tasks
• It is impossible to load several calendars with different passwords on the same server. (bug 247486)
• "By weekday" and "by day" recurrence types (such as "recur on the last weekday of the month") are not supported. (bug 322458)
