How to get support for Thunderbird.
Ask a Question
You can ask a question on the support website. Remember to be courteous, as most of the people providing support on this site are volunteers and fellow Thunderbird users like you!
Donation Support
If you have a question about a donation you've made, you can contact us over at the Donor Help page. Our donor care team will be happy to assist you! The donor care team does not offer technical support, for that see our support page.
Live Chat on Matrix
You can chat with other users and members of the Thunderbird team on the #thunderbird channel on Mozilla’s Matrix chat server. You can log onto Matrix by following instructions on the wiki. Matrix support is also available in Thunderbird!
