How to Contact Thunderbird Customer Support?
Mozilla Thunderbird is a free, open-source email client that offers powerful tools for managing emails, calendars, and contacts. While it's known for its stability and performance, users may occasionally run into technical issues, setup problems, or configuration errors that require assistance. However, because Thunderbird is open-source and community-driven, the support system works a bit differently from traditional commercial software.

In this complete guide, you'll learn how to contact Thunderbird customer support, what support options are available, and the best ways to get help with your issue.
Is There Official Thunderbird Customer Support?
Unlike paid software, Thunderbird does not offer traditional customer support via phone or live chat. Instead, it provides community-based support, detailed documentation, and access to experienced users through forums and discussion boards.
Thunderbird is maintained by the Thunderbird Project, which operates independently from Mozilla. The development team and global community of contributors work together to offer reliable support channels that are accessible to all users for free.
Main Support Channels for Thunderbird Users
While there is no direct customer service line, Thunderbird offers several reliable ways to get help:
1. Thunderbird Help Center (Official Documentation)
The Help Center provides detailed articles on topics such as:
Email account setup (IMAP, POP, SMTP)
Common error messages
Add-ons and extensions
Account security
Calendar and contact sync
This is often the best starting point for resolving issues on your own.
2. Community Support Forum
The Thunderbird Support Forum is an active community where users can:
Ask questions about specific issues
Search for previously answered questions
Share tips or solutions
Interact directly with experienced Thunderbird users and volunteers
You can browse existing discussions or post a new question. Be sure to include details like your Thunderbird version, email provider, and error messages to get accurate help.
3. Mozilla Support Community
Although Thunderbird is now independent of Mozilla, the Mozilla Support site still hosts legacy documentation and community discussions. Some long-time Thunderbird users remain active on this platform, and it can be useful for older versions or broader Mozilla-related questions.
4. Bugzilla (For Reporting Bugs)
If you've discovered a technical bug or software glitch, you can report it through Thunderbird’s issue tracking system, which is hosted on Bugzilla. Use this platform to:
Report software bugs
Suggest improvements or features
Track the status of reported issues
Note: Bugzilla is not intended for general support or setup help; it’s mainly for development and troubleshooting bugs in the code.
5. Thunderbird Mailing Lists and Developer Channels
For users comfortable with technical communication, Thunderbird maintains various mailing lists and chat channels for development and testing discussions. These are typically used by:
Developers
Advanced users
Contributors and testers
This isn’t customer support in the traditional sense, but it’s useful if you're contributing to the project or facing a complex technical issue.
