First my email providers web site works perfectly. I called them and double checked the proper settings. I can download my emails no problem. I disabled my antivirus program, and I have tried all the suggested settings and still no send. I installed Betterbird used the same settings Spectrum said to use for thunderbird and it sends and receives no problem so what's wrong with my Thunderbird?

For a week or two I haven't been able to send any email from Thunderbird. I use smtp.gmail.com as my outgoing server, and have it configured using SSL/TLS on port 465 with Oauth2 authentication. I first saw this on an older TB version, but have now updated to Thunderbird 152.0.1 on MacOS Sequoia 15.7.7.

When I try to send email, a dialog pops up saying "Enter credentials" for my account, then "Verify it's you". When I click on Next it asks me to "Complete sign-in using your passkey". I believe at this point another window is supposed to pop up and I can use a fingerprint to enter the passkey, but that window never pops up. I have tried 3 different default browsers: Firefox (my usual one), Google Chrome, and Safari. All behave the same. Firefox might be suppressing Javascript, but the other two certainly aren't.

Is there some system security setting that might be preventing Thunderbird from opening a window in the default browser, or does Thunderbird maintain its own record of the browser? Any other suggestions on how to get the passkey challenge to appear?

I use Thunderbird as a POP server and keep some historic read emails in my inbox as well as archiving others to local folders. I am moving to a new windows 11 computer from an old windows 8 computer. So I exported my Thunderbird profile on the old computer, copied it across to the new computer, installed Thunderbird on it, then imported the profile. All my local folders are there with their historic emails, but there are no read emails in the inbox, only the unread ones ?? Be grateful for any explanation of why this is and how I get them back. thanks Martyn Jones

I've just transferred my profile to a new computer, for which I downloaded TB152 (had been running TB128), and no add-ons/extensions work. Of course many were rendered inoperative with the update, but that's not the issue, because:

1. Even those which claim to be compatible, or were updated since the transfer for the purpose of extension compatibility, do not work.
2. Moreover, when I invoke the Add-ons Manager to inquire about the various non-working extensions, none of the links (which can be seen and read by the OS), can be invoked or even copied (to be, for example, pasted into a browser window).

I went through the standard [[Mozilla Support diagnostics|https://support.mozilla.org/en-US/kb/hyperlinks-in-messages-not-working]] and found no answers. Can someone suggest a next step?

Trying to understand why this problem is related only to the extensions, I examined the profile's "extensions" folder. There are 40 .xpi files (same as the number of mostly-disabled (and mostly-expired) extensions in the Add-ons Manager), along with a subdirectory named "staged" containing 7 empty folders with what appear to be .xpi filenames - though none of those empty-folder-filenames match any of the .xpi files in the parent "extensions" folder. Because the "staged" folder has a recent timestamp (apparently the last time TB shut down), it seems to have some significance to TB operation - but what can be the use of it is more than I can see. What is the significance of that folder and its contents?

Two final (and possibly related) questions about this "extensions" folder:

1. Is there any way to relate the <filename>.xpi to the name in the Add-ons Manager?
2. Since nothing in the "extensions" folder identifies which are enabled, there must be some file containing a functional description of the folder's contents. Where would that be?

Grateful for any pointers, -John

Hello,

I'm hoping someone can help me recover a local task calendar.

Environment Thunderbird 152.0.1 (aarch64) macOS Local Thunderbird calendar (not Google, Exchange, or CalDAV) What happened

Several months ago I deleted a local calendar because I believed I was no longer using it. Unfortunately, that calendar contained all of my Thunderbird tasks.

After deleting the calendar:

the local calendar disappeared from Thunderbird all of my tasks disappeared I have not created any new local tasks since then

What I have recovered

I have an older copy of my Thunderbird profile from before the deletion.

From that profile I have:

calendar-data/local.sqlite prefs.js

I inspected the SQLite database and confirmed that it contains 394 tasks.

The task records appear intact, including task metadata such as:

titles categories completion information recurrence tables alarm/snooze tables related Thunderbird calendar metadata

All of the recovered tasks belong to the same calendar ID:

8420c0c3-6b20-436c-a39b-d4183d2665e1

Current profile

My current profile contains only my two iCloud CalDAV calendars.

The deleted local calendar no longer appears in prefs.js.

Because of that, the task database appears to be orphaned.

What I have already tried Restoring the old local.sqlite Creating a new local calendar Exporting the tasks to ICS and importing them

Thunderbird reports:

"No importable items found in the file."

My question

Since the task records still exist in the original local.sqlite, is there a supported way to:

recreate the missing local calendar definition so Thunderbird recognizes the existing tasks, or migrate the orphaned tasks into a new local calendar?

If necessary, I'm happy to provide:

the recovered local.sqlite the current prefs.js any additional profile files

My goal is simply to recover the 394 tasks into my current Thunderbird profile without losing any data.

Thank you for any guidance.

Yahoo.com decided to be jerks and changed everything to get into our email. I was overseas at the time and got it taken care of for the laptop I was using on my trip. When I got back home I updated the rest of my computers to the new settings. However, this computer I am on, my secondary desktop, absolutely positively does NOT show Oauth as a choice for smtp on my Pacbell.net account which has to go through Yahoo.com. All the other server settings are working fine. I can get email, I just can't resply unless I go to my Netscape.net account which goes through AOL. It shows Oauth for AOL. The rest of the computers, and even a new laptop, all work just fine and all are on version 152.01. Even SeaMonkey email has Oauth for smtp but they have done a terrible job of keeping it updated that I can't use it for my Pacbell.net account because I can't enter the new password. Everything is a blank screen for log in and password entry. I am getting tired of having to reply to messages on my Pacbell.net account through the Netscape.net account. What can I do short of a clean reinstall of windows?

I've had a Thunderbird email account for years. My laptop quit, so I've set up the account on a new laptop. I discovered that I hadn't saved my Thunderbird password, so I followed the procedure for "forgot password". This included a new p/w, and I also got a Mozilla PIN (for future Microsoft Password Manager use), and got a Mozilla Account Recovery Key, again for future use. But I can't log into my Thunderbird account. I get the message "Authentication Error" (Wrong p/w, email, etc.) Changing IMAP / POP settings didn't help, though I did go with the recommended IMAP setting.

Any suggestions?

I've completed all the required information when trying to add an account to Thunderbird. The Account Hub finds my email address at Posteo and loads the configuration found out the provider. I then add my password, which I know to be correct as I've only just created it. But Thunderbird keeps telling me there is an "authentication error". I'm at a loss to know what the error is.

Really weird problem with a friends thunderbird setup.

All of a sudden my friend was unable to get here emails. It kept saying the password was incorrect. Of course she didn't know her password but it was saved in Fire fox. Found the password and verified her centurytel webmail works. So put it in Thunderbird and still give me an error. I then decided to install Thunderbird on my personal laptop and everything works fine. So I decide to do a clean install, deleted all profile folders and everything. Reinstall Thunder bird and get an "Authentication error". I tried disable all her firewalls on her computer (Windows 11) and disabling the firewalls on the router/modem itself. It still doesn't work. I think next thing I will try is my laptop that has thunderbird installed with her email account.

Any other ideas?

I don't have an error code.

I am using TB 152.0.1 on Windows 11 Home 10.0.26200 Build 26200 I want to have TB on my Galaxy Tab 6 lite, and/or Huawei P20. I have the app installed on both devices, but whenever I try to scan the QR code under 'export for mobile', neither device locks onto it.

I know this problem has been reported before, but what I can do to make it work? Is there a setting I need to check/change, what is that setting, and where do I find it?

Grateful for any help, thank you

Hi,

I was wondering the reason for the change in version 154 about changing the minimize to tray behaiviour when pressing the minimize button to minimizing when pressing the close button. Is there a standard? Why not make it a 2 way option, for users that prefer the older function?

Thanks.

Hi,

I use Thunderbird 152.0.1 (64-Bit) and I only have three items in the files & attachment section of general settings (JPG, PDF, Excel). How can I add more items, for other file types? Is there an easy way to do this or does this mean I have to deep dive into the configuration of Thunderbird?

And would it be possible to add an item to declare that website links in e-mails have to be opened with Firefox in private mode, which is not the standard browser on my machine?

Thx!

TBird connected to AOl fine for several years. Now, today, TBird tells me that my AOL password is incorrect. I changed the AOL password but TBird still does not work. I can sign on to AOL just fine using Chrome and going to the AOL web site, but TBird will not sign me in. Please help.

I am not able to send an email. The send tab is hidden or missing. Tried restorying it but it did not work. Please HELP.

THANKS

I am using Thunderbird for my emails since gmail will no longer support my business emails. I was able to access my sent emails up until April and now I am no longer seeing sent emails show up in the sent folder. Please provide easy to follow steps for this. I need to be able to access my sent emails.

I transferred data to a new computer. I have two emails, when I click 'New Message' one email has a line below the subject line that allows me to set Paragraph, Variable width, font color, Font size Bold, etc. the other does not have the line where do I turn it on at?

I had logged this issue in early 2025 but it has never been resolved and still exists.

I received a reply today, Tuesday 7th July, from Wayne Mery, who said "If you are still having problems when using a newer version, please post a new question and we'll take a new look at it.". as the original post has been archived.

So, here are the details:

"I am currently running Thunderbird 152.0.1 (64-bit) and I don't get an automatic prompt for updates and haven't been getting them since I updated to Supernova and now Nebula.

I have the settings set to Check for updates, but let me choose whether to install them, which is the setting I have always had and I used to get automatic prompts for updates with a window opening to show the details of the update as I get in Firefox.

Can someone tell me how to get these automatic updates back."

I have attached a screenshot of the original version.

Thanks.

Hi, I have two accounts in my Thunderbird. They are Gmail (regular gmail account) and CFCC (an institutional account). The CFCC shows up in my Unified Folder list but the Gmail does not. Is that normal? The main Inbox is showing all incoming emails from both accounts so no performance issues, just wondering how to get rid of the CFCC (if that's possible) to eliminate clutter. Thank you. GES

I am experiencing an issue where clicking links inside Thunderbird emails forces Microsoft Edge to launch a completely brand new window with a blank profile (no extensions, default settings). It does not open as a new tab in my active window.

My environment details:

• OS: Windows 11 (Version 25H2) • Default Browser: Microsoft Edge (Only one profile exists under edge://settings/profiles, no Workspaces used). • Thunderbird version: Latest stable release.

When Thunderbird passes the HTTP/HTTPS link to Windows, Edge seems to ignore the standard "Default" user data directory profile and launches a temporary or guest-like profile container instead.

Is this a known bug in how Thunderbird handles external URI handlers, or is it an Edge registry/default app assignment issue? Any help or workaround config settings would be appreciated. Thank you!
