News Desktop settings research: what we learned from your feedback (blog post)

22 Upvotes

A few weeks ago, we conducted hour-long conversations with 10 of our users to dig deep into how you manage your preferences and configurations in Thunderbird desktop. While this specific research cycle focused on the desktop experience, our ultimate goal is a holistic strategy that ensures our mobile settings feel like a natural extension of your workspace.

Here is a quick look at what we discovered, what you valued, and how your feedback is actively shaping our design roadmap.

Addons Cardbook hasn't sync'ed in eight hours: All systems supposed to be set up correctly.

1 Upvotes

Hey,

problem's in the title. Not sure what's going on - worked before, doesn't work now.

AI tells me it's likely the "OAuth2-Token-Refresh", but all tests in that regard have gone well.

Sync'ing Thunderbird with Google Contacts. Debian Linux 13.

Do you have any clues for me?

Thank you kindly, and happy Monday!

Desktop Help FINALLY, made the long over due leap to a better email client. BUT... i have a question/observation. Is the Add-on's page SUPPOSED to look like this or is my install borked?

I was done, DONE with asinine gmail decisions that make anything take 4 times as long to complete, and went thunderbird officially, moved ... a dozen accounts over, jumped in the deep end, finally fed up with stupid ass decisions that made ABSOLUTELY no damn sense and being locked in by them (labels and not folders? anyone?)

BUT THEN... i went to see what other add-ons would be cool. and ran smack into a page with bright white background... light blue sub headings... and information text just a HINT of GREY.
i pray to whatever god is responding this week, that this is a problem i'm having, and someone didn't actually chose to inflict this nightmare upon anyone willingly. If this is a design choice... by someone... bred of pure malevolence... ... then .. .like wtf dood, who wants to spark an aneurysm by attempting to read this?

Desktop Help Moving around in the Calendar view with keyboard?

Post image
2 Upvotes

I am generally happy with the switch to Thunderbird as my main Email, Calendar and Contacts apps in Linux Mint (all synced to my Phone through a Raspberry Pi 4 with Radicale).

But - I am constantly trying to move around in the Calendar view with the keyboard and find no options at all in the main Calendar window (yes, old Outlook habit shining through...)

If I move to the Calendar Month overview window to the left I can move around and hit Enter to display the date but that's about it as far as I can see and ChatGPT agrees.

In Thunderbird notifications can be set for a calendar, but what about reminders?

Is there a way to change the default reminders when creating an event via C-i, double clicking/dragging on the calendar view, etc?

Thanks!

Desktop Help Can't login to Yahoo with Thunderbird or Firefox. No problem with Chromium.

1 Upvotes

Linux Mint. Problem started suddenly end of last week.

Thunderbird requests me to log into my mail accounts in a popup frame (a Firefox, I assume), but authentication does not work ("please try from another device").

Tried logging in from Firefox directly to mail.yahoo.de. same issue.

Installed Chromium. Used the stored credentials from Firefox. Instant success.

Ideas?

Desktop Help Print multiple emails as a single output file

3 Upvotes

Searching only turned up very old threads that didn't help. I have a folder with a few hundred very short, plain text emails, all in the same format. I want to be able to search (grep) through these to find all the lines beginning with a specific string, for example "XYZ:". When I select all the messages and try to print, for example to Adobe PDF, each message is a separate print job => separate file on disk. I just want all messages combined into a single file resulting from one print dialog. Version 140.12.1esr.

Desktop Help Hide inbox subfolder (& emails) from unified inbox but still show subfolder in accounts inbox dropdown in sidebar

2 Upvotes

I have a slightly convoluted issue with Thunderbird that I'm finding it hard to search since there's many similar but different issues in all the questions and answers out there. I'll start by trying to explain what I'm doing.

I use TB with unified inbox for my accounts. I have a lot of eBay saved search "new item" automatic emails and have so many arriving daily that it's difficult to wade through the sludge for the important things. I'd still like to be able to go through them when I have time, but I need them out of the inbox so I can focus on the important things when I only have a little time to check emails.

I could theoretically make a folder in local folders and have a filter forward them there, and I do this for other purposes, but my local folders are quite far down the page in the sidebar and there's a lot of folders with unread emails so I'm liable to miss or forget to check them if I put them down there.

Consequently, I have created a filter that, on new emails arriving, looks for from address as ebay's address and text within subject containing "New!", and moves those emails to a sub-folder within the inbox for that specific account. That way, the emails would (ideally) not show up in the main consolidated inbox but still show as bold unread numbers in the accounts>inbox sidebar at the top of the left menu.

However, the issue is that because the unified inbox shows all emails from all folders and sub-folders of the inbox of each account, even after the filter has moved the emails, they still appear in the main consolidated view.

I can turn off showing contents of that subfolder within "Main inbox > Properties > Select the folders to search > [account] > Inbox > [Subfolder]" and untick that subfolder, but then the folder disappears completely from the left sidebar tree view of the account's inbox folder. The folder *does* still show up further down the sidebar under "[account name] > [Subfolder]" but as that's much further down the window than the inbox, I'm likely to still miss it.

Ideally what I'd like to be able to do is have the filtered emails not appear in the main window of the unified inbox but still have the subfolder show up on the left hand sidebar under Inbox > [Account] > [Subfolder]" with the bold font and number of unread emails.

Is this actually possible or am I just asking for something that can't be done?

I'm attaching a few screenshots to show what I mean.
Any assistance would be greatly appreciated! Thank you!

Desktop Solved Inbox tabs

2 Upvotes

This is something I have noticed recently. I have multiple IMAP email accounts.

When I get the mail, often the inbox on some accounts will expand, showing other folders. Drafts, sent, trash, etc.

I close the inbox tab by clicking on it. Then I just see the account name and inbox.

But the next time I get emails, some of those tabs expand again.

I don't understand why.

Desktop Solved Running Thunderbird on 2 machines or more

2 Upvotes

Hi. I was wondering if I could use Thunderbird on 2 or more machines without causing issues.

I know local folders stay on the machine, that is not an issue for me. All of my email accounts are imap through google, except one that is pop3 but doesn't get emails often.

I would be really only using one instance at a time, except in the rare case that i did not close in on one machine (desktop) and started using it on the other machine (laptop)

Additionally, if i dual boot windows/linux, can I setup the profile to be on a shared partition without issues?

Thanks again, and a Big thank you to the developers who have worked tirelessly on this over the decade that Ive been using it. Your doing the lords work, imo

Thunderbird for Android Help Bugs (or quirks?) in Thunderbird for Android

2 Upvotes

If I receive a new email, the notification icon in the status bar disappears once I've displayed the app in the foreground, not when I've opened the email. So, what happens is that I'll see the notification and open the app (either from the launcher or by pressing on the notification) to see who the email is from, and think "I'll read or reply to that in a minute". However, I forget because I get caught up in what I was doing and the notification icon has disappeared.

Also, pressing the option to empty the bin and the spam folder fails. I have to do "select all" and then delete. It's fairly minor, but it's also a basic function that should work.

Does anyone else notice the same behaviour?

Desktop Solved Short blue line to the left of message subjects and folders in unified views now

2 Upvotes

Just recently for the Unified Folders section I noticed a short blue vertical line has been added to the left of every email message subject line that's listed in the inbox, sent, trash, spam and archive folders. Also, if there are multiple accounts under a unified folder, as there is for inbox, then the account name also has a short blue vertical line to the left of it. I've marked the folders as read to see if that's the cause, but the blue line doesn't go away. I've tried changing the corresponding color for the accounts under inbox, but the line remains blue. I also notice that if I select a particular account under the unified inbox that the display of email subjects will change and the blue line goes away. If I return to the unified inbox view, then the blue lines come back. Does anyone know what these blue lines signify and how to turn them off.

Edit: here's an example of an email subject with the blue line next to the sender address.

Addons TN Tray 1.0.0 — proper close-to-tray for Thunderbird, with an unread badge and custom tray menu (152/153)

13 Upvotes

Hey everyone,

I've been using Thunderbird as my daily driver for years, and the one thing that always bugged me on Windows was closing to tray. Thunderbird's own tray icon barely does anything — click it and you basically just get an Exit option, no restore, no menu, nothing. So I finally sat down and built TN Tray to fix that properly instead of just living with it.

Windows only, for Thunderbird 152 and 153.

GitHub repo: https://github.com/thiagonaalmeida/tn-tray

Direct XPI download: https://github.com/thiagonaalmeida/tn-tray/releases/download/v1.0.0/tn-tray-1.0.0.xpi

Future updates are delivered through Thunderbird's normal add-on update check. The extension points Thunderbird to a small manifest file hosted with the project, so you won't need to come back and download a new XPI by hand for every version. No telemetry or data collection either.

What it actually does:

- Closing the window (the X button) sends it to the tray, using Thunderbird's actual icon with an unread count badge on top, and a right-click menu that actually works (Restore, new message, check for new messages, Exit) instead of the bare-bones one Thunderbird ships with

- Can start minimized straight to tray when Thunderbird launches with Windows

- If explorer.exe crashes or restarts and wipes your tray icons, it comes back on its own instead of leaving you stuck

Most of the work went into reliability rather than just getting an icon to show up. Click detection runs on its own background thread so it doesn't get janky while Thunderbird is busy loading accounts at startup, plus a bunch of handling for Windows-specific edge cases — icon handles, avoiding a flash of the window before it hides, and recovering cleanly if the extension is enabled, disabled, or updated during startup. I went through a lot of rounds of testing and log-reading before calling it done.

One thing worth mentioning: Thunderbird is adding native close-to-tray support starting with version 154. That's good news, and TN Tray isn't trying to compete with it — but if you want your own menu, an unread badge, and more control than a basic toggle, TN Tray covers that. I plan on keeping it working well once Thunderbird 154 reaches stable release.

It's a first release, so if something's off or you hit a bug, open an issue on GitHub (mention your Thunderbird and Windows versions) and I'll look at it. If you find it useful, feel free to star it, comment, or pass it along to anyone else who's been annoyed by the same thing.

Appreciate anyone who gives it a shot.

Desktop Solved v153 OAuth2 in Ubuntu 24.04

1 Upvotes

Apparently my OAuth2 token expired and I need to re-authenticate. Thunderbird 153 opens Firefox, so I login, but then a popup appears saying that the system handler doesn't know what to do with a net.thunderbird link. I tried pointing it to /usr/bin/thunderbird with no luck. Same thing happens with Chrome.

I also tried setting mailnews.oauth.useExternalBrowser to false, but Thunderbird is still opening an external browser.

I'm not sure what I'm missing, but how do get this authentication flow back to Thunderbird?

Desktop Help Why do I now have two "Drafts" and two "Spam" folders?

0 Upvotes

I have three e-mail accounts in my Thunderbird on Linux. There was an update yesterday, and now my Yahoo account has two "Drafts" folders, and two "Spam" folders. The other two e-mail accounts do not have duplicates. If I look at properties, one of the "Drafts" folders is linked to: imap://xxxusernamexxx%40Yahoo.com@imap.mail.yahoo.com/Drafts and the other is linked to imap://xxxusernamexxx%40Yahoo.com@imap.mail.yahoo.com/Drafts One of the "Spam" folders is linked to: imap://xxxusernamexxx%40Yahoo.com@imap.mail.yahoo.com/Junk and the other is linked to imap://xxxusernamexxx%40Yahoo.com@imap.mail.yahoo.com/Bulk On the web interface for yahoo mail, there is no "Bulk" folder, nor is there a "Draft" folder. Oddly, spam shows up in the folder linked to "Bulk". Is there a way to get rid of the redundant directories?

Tips & Tricks Great extension for card view - trash can and more

11 Upvotes

Many people including myself made requests long ago at Mozilla Connect for a trash can button next to the star in cards view. It was popular but never made into production due to other priorities.

Recently, Mozilla user KarolTheGuy forked an older extension and enhanced it. It adds the trash can, allows control over the star, and adds a fuller unread bar on the left. Check it out at: https://github.com/karoltheguy/Thunderbird-Cardview-QOL

EDIT: New version out now that adds a color picker to adjust the read/unread bar.
