Hi, somehow thunderbird forced me to use OAuth for caldav and carddav. (v140 on linux) Unless I've probably missed something this approach doesn't seem to have considered that people might use more than one device. In the past I had an application password per device with my mail provider. That password covered imap, smtp, caldav and carddav. The application password I could set with a specific name at my mail provider. If the device was lost, compromised or whatever I just deleted that one application password at my mail provider, problem solved.

Now a regular thunderbird setup has the application password for mail and 2 OAuth records per device under "Connected Apps" at my mail provider. But it is not possible to see anymore to which device the OAuth record belong, as there is nothing device specific coming along with these OAuth records, just an IP.

With that perspective OAuth weakened my security options, as I can only guess which OAuth record I have to delete in an emergency case. Did anyone who implemented that with Thunderbird considered that people may have more than 1 device? Maybe even more than 5 devices?

That OAuth approach looks unmanagable to me. Is there a way to switch OAuth off in thunderbird, until it becomes more useable in >1 device setups?

Cheers Tjareson

I noted, that credit cards autofill works, but on ~50% of websites it fails. I can see the autofill dropdown, but if I select any card, no fields are filled. Manual filling works. One of examples: https://ipn.paymentus.com, but there are many. Again, on some websites it works just fine.

Another issue - I cannot edit cards. Settings->Payment methods->Manage, then select a card, press "Edit" and nothing happens.

Context: version 148.0 (64-bit), Canonical snap build (crap, I cannot DISABLE snap build and totally switch to deb!!!)

P.S. I really miss feature to add "aliases" for cards...

I have Version 140.8.0esr | Released February 24, 2026, for Linux Mint (up to date)

I have a CardDAV address book on a Nextcloud instance that i want to sync to Thunderbird.

When i open Address Book and the clikc on " Create a new address book" the Account Hub modal window opens. None of the 4 options (including Add Remote Address Book" do anything, i.e. I can click as much as I like but nothing happens.

Subject: Request for Custom Provider Support or Grok Integration in Firefox AI Chatbot Sidebar

Detailed Description: I am exploring the new AI Chatbot sidebar feature in Firefox (Ubuntu build). As a practitioner in the deep learning field, I am particularly interested in the flexibility of the Web-view container used for these AI integrations.

Currently, the feature appears to be a curated list of providers (ChatGPT, Claude, Gemini). I would like to request the addition of Grok (by xAI), or more importantly, a Generic Provider Framework that allows users to manually configure custom endpoints.

Technical Specifics & Implementation Questions:

   Manifest Configuration: Is the sidebar AI provider list controlled via a remote settings push, or is there a local about:config or JSON manifest (e.g., within the browser resources) that can be modified to include Grok's web URL?

   Context Injection: How does the current sidebar handle DOM context for features like "Summarize this page"? If I were to manually add Grok via a side-loading method, what are the required API hooks for it to achieve parity with the built-in providers?

   User Agent & Authentication: Are there specific CORS policies or User-Agent strings enforced within the sidebar's iframe/browser-view that would prevent Grok’s X-auth or real-time streaming (SSE) from functioning correctly?

Use Case: Integrating Grok’s real-time information retrieval directly into the browser’s native sidebar would significantly optimize research workflows involving live data, which is a key differentiator from the currently supported models.

Menu: Message>attachment>delete all

When delete all attachments for a message, when delete all attachments, auto move to the next message.

This behavior is annoying, usually I first delete all attachments and then reply but message position is in the next message.

This behavior is for example for version 140.7.1esr and 140.8.1esr.

102.15.1 work fine.

Listen I have a profile in another partition in Mint and want to transfer my Bookmarks/profile etc to my new 22.3 install but far too complicated. I also have a previous Key which I no longer wish to use as it has deleted all 20 years worth of messages. Please please please just set up my profile again oFirefox or then revert by to the one from 2025 Mint 21.3 Thomas McM Rbold textamos de Deus

I would like an apple (icloud) account to thunderbird, but it doesn't work the automated way. I changes password and made sure that account data and password fit. Anyway I got an error message and wasn't able to connect. I had no issues with outlook and the apple account, so I'm wondereing what I need to adjust or add. I want to finally switch all my accounts and systems to open source and getting them connected is my first step. Any help would be appreciated. - Thanks in advance!

to test my new proton.com email service I sent a message from my proton.com account to my gmail.com email box, the message is not displayed in my gmail inbox. The reverse operation works (from gmail.com to proton.com inbox). Why?

I'm running Linux devuan: Linux MikesPI 6.1.93 #1 SMP PREEMPT Mon Dec 8 02:37:53 CET 2025 aarch64 GNU/Linux and Firefox 140.4.0esr (aarch64).

For years now I've been downloading and saving Yahoo quotes as csv, now for the last week Firefox wants to save page image poping up an extra window that must be refused before I can continue using Firefox. Hopefully someone can tell me what new option in about:config can be turned off to stop this. Thanks, Mike

Hi all, My Thunderbird settings are suddenly being ignored. First the order of the emails was altered to ascending instead of descending then the adaptive Junk setting stopped working so that although the correct emails are marked as junk they are left in my in box and I have to manually move them. I have checked that the settings are still as I chose but they are being ignored.

The grammar-checking extension "Verificador Ortográfico para Português do Brasil", licensed as GPLv2, has a link that redirects to a SourceForge category listing. It is nowhere to be found there. It has a contact email, and I've sent a message to them asking for the missing information.

The MPLv2 license requires disclosure of the source code, and so does the GPLv2. What can Mozilla do about it?
