Contacting Thunderbird Customer Service Center

Thunderbird is the mail client from Mozilla. Mail clients collect emails from various email addresses so you can access all your messages from one application. The basic function of Thunderbird is to send and receive messages, but there are advanced options available as well, including automatic responses.

Phone Contact Numbers

Mozilla is a company that specializes in the development of free software and applications like the Firefox browser and Thunderbird mail client. When a company offers free applications they often forgo phone customer service support for email and social media support. Call centers are expensive to man. There are no phone numbers listed on the Thunderbird website, but we were able to locate the corporate phone number.

Mailing Address

Thunderbird customer service doesn’t necessarily have a mailing address, but you are more than welcome to send Mozilla a message by mail. The Mozilla corporate mailing address is available on the contact and support pages of the Thunderbird website.

Mozilla Corporate Attn: Thunderbird Customer Service 650 Castro St Ste 300 Mountain View, CA 94041

Official Website

You can find the official website for Thunderbird on the Mozilla website at To access customer support click on the Support link at the bottom of the page. From there you can search the Thunderbird customer service database for questions other customers have already asked. This is the fastest way to reach a resolution, but it is not always the most effective way. A more effective way to reach Thunderbird customer service is via social media. While there is no Thunderbird page, there is a Firefox page on Twitter and Facebook.

Customer Service Email

We looked high and low, but we were unable to find an email address or email form for Thunderbird customer service. We did find an Ask a Question page. To send your question click on Fill in the topic, title and details and submit. The question is submitting to a forum, not to the customer service team, which is why you’re asked to give the topic a Great Title.

Our Experience

When we looked through the official website, we noticed several pages of information, including a page similar to a FAQs page. One thing we didn’t notice was details relating to privacy and security. This was the topic of conversation when we contacted the customer support team. The call center was easy to reach. The total wait time was less than 2 minutes. After the agent answered the call, we wanted to know what steps the company has or is going to take to secure our information.

The agent explained that the information collected by the company is not used by third-parties. The agent sent further to inform us the information collected is used by the company to better improve the services, not violate customer privacy. We are leased with the customer service team standing up for Thunderbird. They are knowledgeable and ready to assist, no matter what the question or concern. We would love to hear your story relating to Thunderbird customer service. Share you comments below.

  1. Received Thunderbird server error referring me to a log which I know nothing about and/or cannot access. Please help, as I am unable to access my Thunderbird email account.

    E. werve

  2. when will the contact manager be re-designed to allow a contact to have more than 2 email addresses? I will return to TB when it does.

  3. The e-mail “send” button was replaced with “send later”…NOT MY REQUEST.
    How do I get :”send” back?
    I have no way of knowing IF my e-mails have been sent or WHEN.

  4. this by far the worst company I have ever dealt with I can not get a real person to answer my questions all I can get is emails and there any good I need to put a like us button on my email but I can’t get it and know one from this company is there to answer my questions you will never get my referral

  5. I think your thunderbird support sucks……I can not find a fix my thunderbird e-mail……can not find a phone number so I can call support….Thanks for nothing….

  6. The Thunderbird help/support is non-existent. The site is a waste of space and useless. I attempted to had a gmail account to my email; changed the PW three times and still the popup demanding a password would not accept any of them. I finally deleted the gmail aaccount with google in the hope that the popup would go away; it has not. Not only do I no longer have my gmail account, I am still aggravated by a popup window demanding a password for an account that has been deleted. This is not a way to run a railroad!

  7. How does a customer get help/support for Thunderbird or Mozilla? What is passed off as a help/support site is less than useless and there is no way to email or call for same.

  8. Why so hard to contact Thunderbird support to leave a comment? There doesn’t seem to be any such thing as good customer support in the US anymore. Ever deal with Comcast?
