hello, every time i start thunderbird, i'm presented with a tab that shows me the privacy policy. EVERY.SINGLE.TIME. i don't need to read it every time; reading it once and confirming is enough. but there doesn't seem to be any way to confirm, or disable this annoyance. how can i get it to stop? is there a setting somewhere, or registry entry i can change?

Thunderbird Desktop Version 115.18.0esr

Login to the server pop.gmx.net with username "..." failed.

I have several accounts with GMX. Two work, and the other two display the above error message. Everything works when I log in via a browser, but not in Thunderbird. The account settings are identical for all four accounts except for the password and username.

What can I do?

Thank you in advance.

hi, if i sync 2 t/bird installs which one will install its personal data on the other pc?. the same question also applies to my f/fox install if anyone knows

win 10 tb145.02

thanks very much if anyone knows

All, recently set up email accounts and all was well. Used TB years ago & liked it for its ease. Now my signature is not working (set up with 'attach signature from a file instead' option FYI). Tried everything I can think of, disable add ons in troubleshoot mode etc. deleing & re-adding it. No new add ons have been added before this happened, they were added prior to setting up signature. And worked fine initially. Thoughts and please keep it simple for someone very old lol - pic attached for help perhaps?

TIA and appreciated

I used to be able to see a running account of the number of messages left to move or to delete.

If this is still available, how do I turn it on?

Thanks.

Hello,

I am requesting immediate assistance with a critical and persistent problem in Thunderbird.

For my Google Workspace account max@dantanas.com

, Thunderbird refuses to create or recognize a Junk/Spam folder. This is not a cosmetic issue — it directly affects email safety, filtering, and daily usability.

Summary of the Issue

Thunderbird does not automatically create a Junk or Spam folder for this account.

Attempts to manually create a Junk or Spam folder fail or are ignored.

Thunderbird’s junk filtering settings for this account are disabled or inaccessible, making filtering impossible.

Other clients (Gmail web, Outlook, mobile apps) create and use a Spam folder normally, which shows the problem is specific to Thunderbird.

This problem has persisted across restarts, folder repairs, and full account removal/re-addition.

Why This Is Critical

Without a Junk/Spam folder, Thunderbird cannot move suspected spam anywhere, leaving the inbox vulnerable.

The built-in adaptive junk filter becomes unusable.

Thunderbird does not comply with Gmail’s standard IMAP folder structure.

This issue prevents Thunderbird from functioning as a secure, reliable mail client for this account.

Steps Already Attempted

Removed and re-added the account multiple times.

Forced folder synchronization.

Repaired folders.

Reset folder permissions in Gmail.

Verified IMAP settings (X-GM-EXT-1, special-use flags, etc.).

Tested other devices — only Thunderbird fails.

Expected Behavior

Thunderbird should automatically recognize Gmail’s [Gmail]/Spam folder as the Junk folder OR allow me to assign one manually.

Instead, Thunderbird behaves as if the account is not permitted to have a Junk folder at all, which is incorrect and breaks essential functionality.

Request

I need help determining:

Why Thunderbird is refusing to create or map a Junk/Spam folder for my Google Workspace domain.

Whether there is a known bug with Gmail Workspace integration that causes Junk folder support to fail.

How to force Thunderbird to recognize or create a valid Junk folder.

Whether this issue requires special IMAP flags, folder mapping changes, or intervention from Thunderbird developers.

This is not a minor inconvenience — it prevents Thunderbird from acting as a secure or usable email client for this account. I would appreciate prompt assistance or escalation.

Thank you, Max Makowski max@dantanas.com

I can no longer send messages through the email client on one of my accounts using Thunderbird, which no longer recognizes my internet service provider's password (but it does receive messages). Everything works fine with my other accounts.

Thank you for your help.

I am using Thunderbird 115.5.2 (64-bit) on an older iMac on OS 10.12. I have four email address accounts, all gmail, and using POP. I have stored emails I wanted to keep in sub folders in Local Folders. This has all worked well for years.

Yesterday I lost lost all content from some of the subfolders in Local Folders, while some retained some content and a few seem intact. I also lost most emails that had arrived in the inboxes in the last week. The folder pane still shows the accounts, with their own set of folders. As usual, the inbox folders are highlighted with the number of new emails downloaded from the Gmail server to each address, but I can not see them in the message pane, or find them anywhere else. I sent a test message from one of my addresses to another – It didn't show as sent in Thunderbird, but did go through the gmail server and the message count of downloaded messages on the recipient address went up by one, but I couldn't see the email. Then I tried clicking on the folder "properties" then 'Repair Folder' but nothing happened, although the information on that window showed the number of messages and MB that I would expect to be in that folder, rather than what was there, which presumably means they may still be in there somewhere? I would be very grateful for help – I'm not tech savvy and feeling completely lost.

I am sending a message with Thunderbird through my email server Yahoo. The sending has worked flawlessly until yesterday afternoon; I am getting the following error.

Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) smtp.mail.yahoo.com timed out. Try again.

This works fine with Outlook but not Thunderbird since yesterday afternoon.

Hi everyone - and big thanks in advance for considering my request: I have/ had windows 11 on my old machine and windows 11 on my new machine; because my 'old computer' is not running anymore at all (liquid damage), I can no longer start Thunderbird and follow the 'export tool function' (https://support.mozilla.org/en-US/kb/thunderbird-export) and thus can only do the manual transfer (https://support.mozilla.org/en-US/kb/moving-thunderbird-data-to-a-new-computer); I didn't think that I would need to go through the export tool steps when I saved the Thunderbird profile folder regularly as backup on the cloud; yet when I started Thunderbird on my new machine following the above steps by moving the Thunderbird profile folder manually, the result is that - although Thunderbird is 'running' and the mailbox is functioning properly - the key folders are empty (i.e. the sub-folder structure is completely lost, in fact there are no individual emails at all); the issue seems to be that the size of the Thunderbird profile folder is too large (the "Profiles" folder has a size of 20.5 GB) for doing this transfer via copy & paste of the Thunderbird profile folder from the cloud (I also tried USB) to the new machine; I understand that the size issue via the manual transfer could be 'overcome' just by starting Thunderbird on the 'old machine' and following the above steps explained under mozilla support; yet that's no longer an option; what could I do please?

I have a Thunderbird account on my private laptop and need to move certain files and address labels to Thunderbirds on a new laptop. Can you please advise how this can be done or if it not possible to copy individual folders. Thank you.

Up until today I have been able to send emails(with attachments) from my laptop to my cell phone. Now when I want to send an email I receive an error message saying" An error occurred while sending mail. The mail server responded:(VO-1)Message blocked due to spam content in the message. Please check the message and try again. I tried several times since and the same result. Thank you.

I have Thunderbird installed on my business desktop, and also my laptop. Both work well.

However my main usage, for obvious reasons, is the desktop. That's where I usually respond to customers, save the messages for later, etc. The laptop is used mainly when I travel; I can respond to customers who contact me, and let them know I can process their requests when I return.

The problem I'm having: when I receive new messages on my laptop, it immediately deletes them from the server. They never appear on my desktop, making it much harder for me to process their requests later on.

This doesn't happen the other way around. When I open Thunderbird on my laptop, I receive all the recent e-mails that have already been viewed on my desktop. I don't mind that so much, but I have a problem when the laptop deletes those e-mails to make them unviewable on my main desktop.

I'm sure there's a setting for this, but I can't find it. Can anyone here point me in the right direction?

Hello,

This is the second email I am sending to get help.

I selected my composing font type and color in setting. When I start to compose an email, the font type and text color are shown as I selected. However, as soon as I start typing the text, the color goes to default (black).

Please advise,

Surendra

I used to be able to access filters and set them up, but now I can't even find where they're located to set a new one. I've been through every possible setting, and still can't find the filters. Where are they? They've obviously been moved to somewhere obscure since I last used them (many versions ago, and they still run, I just can't locate them).

Thanks in advance.

I have 2 emails provided by my ISP (knology), I have received no emails since 7:30 on 12/5, the are on the webmail site. The other 2 emails are gmail accounts they are working fine. I am getting a message, "The certificate for imap.knology.net is not valid for that server. Someone could be impersonating the server, you should not continue."

 The fact that the gmails work and knology does not work is a clue but I don't know what it means.

I have contacted my ISP and after 45 minutes they gave up and said they will escalate and get back to me,

with in a couple days! it was on a Saturday.
                                                         Thank you, Mike

PLEASE put the format options back into the email task bar! My formatting needs to be done on a message by message basis. It is time consuming and counterproductive to have to go to settings each time. No matter what I tried in settings, I was not able to get Formatting back into the message task bar. At minimum, I need font, size, list and color options back in the message task bar. PLEASE HELP!
