Lightning is a subproject of the Mozilla Calendar, which deals with the development of a personal information manager software and thus competes with Microsoft Outlook so far leading in this area.
Unlike Mozilla Sunbird, which also constitutes a part of the Mozilla Calendar project, Lightning is not intended as a stand-alone software, but aims to improve the integration of a calendar function in the e -mail program Thunderbird to.
Lightning and Sunbird differ slightly in their functionality. Within Lightning, it is also possible to receive event invitations by e -mail and send. Furthermore, can be viewed birthday dates by using the Expand ThunderBirthDay from the address book of Thunderbird Lightning.
Both programs share a common code base, each adjustments to the stand-alone operation are necessary in Sunbird.
"Lightning " is a working title and not an official product name. Hence the name "Mozilla Lightning " is a misnomer.
The software supports 32 - and 64 -bit architectures for eComStation, Windows, Mac OS X and Linux.
