Welcome to the website of the German Thunderbird community!

The pages of the German-speaking Thunderbird community offer you a one-stop shop if you are looking for support from volunteer helpers around Thunderbird and its calendar, appointment and task management.

What we offer:

Thunderbird Download
On the Download page you will find the latest official version of the Mozilla Thunderbird.

A documentation of the program
In the lexicon system of this website you will find help articles, instructions, questions and answers (FAQ), etc.

Help forums to describe problems and ask questions
The Help Forums are organized into a series of sub-forums that address questions and issues around the email program and related topics. To actively write in the forum (only for this!) you first need a user account. Read the help on how to write in the forums - please respect the terms of use.

What we are not:

We are not the publishers of the program
Mozilla Thunderbird is officially released by the MZLA Technologies Corporation, a wholly owned subsidiary of Mozilla Foundation.

We are not the Thunderbird programmers
The software is programmed by some full-time programmers who are employed by MZLA Technologies Corporation. Additionally, a variety of volunteer persons can and will contribute program code to the software. Much is also taken over by the program code of the web browser Mozilla Firefox for Thunderbird.

We are not a mailbox provider
You will not get an e-mail account or e-mail address from us. For this you have to get one of the well-known mailbox providers.

No Advertisements

There are no advertisements here. Maybe you give the website owner (Alexander Ihrig - aka "Thunder") instead something to be able to finance these sites in the long run. Many Thanks!

Thank you for the support!
