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!

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.

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?

when I click - to open - a downloaded message, the message immediately opens up, (after my click), but the page is all words/sentences to click on to open up to view the actual content of the Page. This is hard to describe.

Before, when I clicked a message in my inbox, the full page opened up. Now I have to do a second click to see the content of the page. Hope this helps describes my problem.

I have re-downloaded Thunderbird, but my problem remains.

Please help me -

Thank you, Jim [edited] @gmail.com [edited email and phone# from community support forum]
