Thunderbird Community Forum

Hello everyone,

I recently saw Mozilla announce that the Pocket service will be discontinued on July 8, 2025, entering an export-only mode, with user data permanently deleted after October 8, 2025.

I’m very concerned about its future. The shutdown of Pocket really hit hard, and it makes me worry: could Thunderbird face a similar fate? Especially now that Mozilla seems to be focusing its efforts more on Firefox and AI browser development, I’d like to ask the community and official team a few questions:

1. What is the current organizational structure around Thunderbird’s development and maintenance? I understand that since 2020, Thunderbird has been placed under MZLA Technologies—an independent, wholly‑owned subsidiary of the Mozilla Foundation—and is managed by the Thunderbird Council. Does this mean Thunderbird operates under a fundamentally different model from Pocket?

2. Is there any possibility of Thunderbird being discontinued, divested, or “down‑scaled” in the future? Does Mozilla have any plans to shrink Thunderbird or shift strategy in a way similar to Pocket?

3. What is Thunderbird’s planned roadmap and how are resources being allocated? From what I’ve seen, Thunderbird is undergoing UI redevelopment (Supernova), monthly releases, mobile client initiatives, and new Pro services like Thundermail, Appointment, and Send. Does this reflect Mozilla’s confidence in its future?

4. How can users and community members show support or express concerns? If we want to help ensure Thunderbird’s continued health and growth, what steps can we take to encourage Mozilla to allocate more resources?

Hello Team Thunderbird You are doing a great job. I use thunderbird regularly.

I wish to contribute through donations.

Can you have UPI payment option in India? I will be donating regularly with that option.

Yours Sincerely

Hello! Would you please tell me how to get access to bugs like https://bugzilla.mozilla.org/show_bug.cgi?id=1958376 ? I’m using Thunderbird for building a mail client and need help with fixing vulnerabilities found in the 136 Thanks!

Hello & Namaste,

I do use Thunderbird and find it extremely useful to collate all my emails at one place. I have contributed earlier and would continue to do so. But I do not wish to provide any credit card information for payment, but there are many other ways of paying thru UPI, Net banking, etc which do not ask for any credit card info. Please review your policy and make it convenient for your customers to make quick payments without asking for credit cartd info. Thanks Renukaprasad Belgur

Please restore View, Toolbars, SEND, ATTACH, etc. i CAN ONLY ACCESS THESE: TO, FROM and SUBJECT. Originally tried restoring via View, Tools, Restore,etc.,but noting worked. I'm an independent contractor and must send and reply to clients . Please help ASAP.

I am concerned that my Pop email setting will default to IMAP when I put add email to my iPhone, causing me to lose all of my current messages. Will there be an automatic default to IMAP?

My latest VISA bill has a $21.40 charge identified as from "THUNDERBIRD EMAIL WWW.THUNDERBI CA". I would like to know what the charge is for as I don't recall authorizing it.

We use an external system for our general day to day business, which has links on the customer details for email. This launches Thunderbird, and puts the email add. in the to field. Is there a way I can get thunderbird to use a template when it receives this command from the external program? The address changes each time, but I want to use the same template to speed up a process.

On my Desktop, I have icons for Back and Restore. I have to close Thunderbird first. Then I click on the Icon, and I can back up or restore. Where can I find the backup and restore program?

Was having a problem accessing my email with Thunderbird. Posted on forum here looking for help and received a response from Matt, a moderator I believe. His reply pointed me in the right direction and things are working properly again.

I received an email notice informing me of Matt's response, but oddly it did not contain a direct link to take me to that particular thread. It took just a few extra clicks after logging into the site and I was able to read Matt's reply. Am I overlooking something in the email? It's not that a big deal but it seems like most any other site will send a direct link to take you to the most recent response.

I have had this problem with FF 139

When I switch to FF 138 - the version which my repo installs, all is well. When I started 138, I was asked to use it as default browser, and links opened as expected.

When I closed 138 and opened 139, I was asked to use it as default browser and links opened a new window of FF with only a blank tab.

When I want to compose an email and put the first letter, eg. J in the 'to' box not all the addresses beginning with J show up from the contacts list. How do I get them all to show? Any advice appreciated.
