Thunderbird gemenskapsforum

Hey Guys,

My Left click to open links from my emails has stopped working. I have to right click and select Open Link. I have tried everything, tried going through some of the config editor options i saw people mention for this issue and its all set to True already. There is no data besides PDF under the settings / attachments section. So cant change anything there. I tried a new profile, no go. I did a full uninstall and delete profile and started again, still same issue.

Left click to open links for everything else on my computer like firefox etc. Just cant open links through thunderbird. It used to work, it seems to have stopped around the same time as the latest update but i cant be sure about that. Only stopped working the last few days,

Windows 11 home, Thunderbird 156.0 (64 bit)

Recently I noted a changed behavior - emails with photo(s) in them used to have the option to right click on the photo and then an option to save-as was offered. The only thing that happens now with a right click is the photo is enlarged or shrunk - no other options.

I wondered if this was an iphone initiated email only problem but it also occurs when I send a jpg photo from my desktop from one email address to another.

I have tried a number of suggestions from the internet without success and my frustration is mounting.

Thank You Norman

Summary: Thunderbird intermittently fails to download certain POP emails that are visible in Mailwasher Pro. Some messages download normally, others disappear from Mailwasher (as expected after a successful POP retrieval) but never appear in Thunderbird. No error messages are shown. Environment: • Email client: Thunderbird (current version) • Account type: POP3 • Anti spam tool: Mailwasher Pro • OS: Windows 10/11 • Mailwasher behaviour: Messages appear correctly in MW’s inbox list. • Thunderbird behaviour: Using Get Messages retrieves some emails, but others vanish from MW without being written into Thunderbird’s Inbox. Detailed Behaviour: 7. Mailwasher shows new incoming messages normally. 8. When Thunderbird performs a POP “Get Messages”: • Some messages download correctly into Thunderbird’s Inbox and disappear from MW (expected). • Other messages disappear from MW (as if retrieved) but do not appear in Thunderbird. 9. These “evaporated” messages are not: • In Inbox • In Junk • In Trash • In Local Folders • In any filter redirected folder 10. No error dialog appears in Thunderbird. 11. Mailwasher logs show the messages were handed off to the mail client (this by omission). 12. The issue has become more frequent recently. Suspected Areas: • Thunderbird POP retrieval logic intermittently failing to write messages to Inbox. • Possible interaction between MW’s “hand off to mail client” and Thunderbird’s POP session. • Potential profile corruption or POP state file corruption (popstate.dat). • Possible Thunderbird bug affecting selective message retrieval. Assistance Requested: • How to diagnose POP retrieval failures where messages vanish from MW but do not appear in Thunderbird. • Whether Thunderbird logs can show POP level message acceptance or rejection. • Whether popstate.dat or Inbox file corruption could cause selective message loss. • Recommended steps to isolate MW interaction vs Thunderbird internal handling.

As a twelve or more years user of Thunderbird, I find it to be okay most of the time. I hate the spam folder that does not learn and I hate threads.

Today all of a sudden, I cannot save photos sent from my iPhone as jpg. I have always right clicked and a menu has appeared. Today, the right click just zooms in which I never want to do when I am trying to save.

I tried searchig online first before coming here. Apple is claiming that Thunderbird developers made a mistake and that is why the right click is not working. AI had me try a bunch of different techniques none of which worked.

When I do save after much effort, the "photo" in my Animals folder appears as the Thunderbird logo instead of the real item itself. The other weird thing is that my folders also do NOT show up where they should when I am trying to save. The menu doesn't give me all the folders as it always has. Instead it just say All Files which is not adequate.

Hi, hoping someone could help as I am struggling to get my information back. I am using Ubuntu Cinnamon.

Thunderbird crashed last night, wouldn't work, tried safe mode. Nothing fixed it. It hung when opening up and after 30 seconds said force quit. So I was forced to reinstall. I did a manual backup but not using the inbuilt tool as I couldn't get into Thunderbird. I just copied the data from username/.thunderbird

After spending a long time uninstalling. Because it reached 78% and then crashed on uninstall. Eventually after reading various pages on the internet I managed to reinstall from the Ubuntu software manager using the latest snap version. (Which I am not sure was what was actually installed previously).

However having used thunderbird for nearly 20 years or so. I have a username/.thunderbird folder. And when I moved to this platform, I have a snap/thunderbird/common/.thunderbird folder.

I installed this new distro 2 years ago, and remember having issues getting my data into the system under Snap. But eventually got it to work somehow back then.

However since reinstalling I cannot see the last 2 years of emails, archives or data. It has launched into a 2 year old profile. I appear to have lost most of the emails from the archive folders (but kept the folders) removed all of the personal folders but then dumped all those emails into my inbox. Giving me 6500 emails that were in various personal folders. (I don't get 6500 emails in a year so don't know what has happened.) It has even changed all of the new dates to the US format, so nothing makes any sense.

I now have 2 Thunderbird profiles, over 12GB in size. And have apparently lost 2 years of my life. But reading support pages, suggests I should be okay because thunderbird doesn't delete data when you reinstall?

I have looked through various other threads which talk about pointing it at the profiles and mail boxes, however nothing works.

Any help much needed.

I have an outlook account that will not install. I get the challenge, to send me an authentication number at another email address, and that says okay, you can close this window and continue, but then at 'continue' in Thunderbird I get an authentication error.

-I have added the email on another computer in Thunderbird and send/receive email, no error -I have added the email in the New Outlook email app and send/receive email, no error -I have added a different outlook account in Thunderbird on this computer, no error -I can log into the Microsoft live email app and send/receive email, no error -I have uninstalled Thunderbird as admin, removed the Thunderbird folders in %appdata% and %localappdata% for both the admin and user accounts, cleared the cache and cookies on the computer and in Thunderbird (including the token), then reinstalled Thunderbird under the admin account, logged into Thunderbird as the user and added the problem Outlook account; same issue. Press Continue and authentication error, even though the challenge screen says everything is connected and okay. Then I install the other Outlook account without any issues.

I am convinced that somewhere on this machine there is something that knows and hates this one email account. It is possibly because the profile file had a problem and I deleted the xulstore.json file per instructions to resolve the problem, but the file is there and the profile is working again for the other Outlook accounts, just not this one particular account.

Any Obi-wan or other wise counsel out there?

Hello people, I've just upgraded my Thinderbird because my inbox didn't load on opening the programme. I guess I have made a huge mistake somewhere in the process, because my whole archive has disappeared. I very much hope it still exists somewhere and that I will be able to restore it with your help. Thanking you in advance, Nele Ysebaert, Amsterdam

Hello. i have latest beta 156.b3 64bit, after updating to beta 3 my tb offer retry passwords to many google acccounts and opening FireFox for again login in to each account. I have turned off checking mails on the start up for them and turn off checking mails, but again and again opening firefox for signing in. i closing firefox but TB not continue checking mail from another mailboxes, they stopped and seems like waiting for signing. i try to manually click for each mailbox "get message", but this no work, could you help me turn off login through firefox?

Od poslednej aktualizácie Thunderbirdu, sa mi prestali zobrazovať vlastné priečinky, ale na na poštovom servri sú viditeľné. Jednoducho ich nenačítalo. Má niekto podobný problém? Jedná sa o poštový server azet-mail.sk

After the crash this morning (19/9/26) I cannot receive or send emails but can access existing emails (open them as well) I spoke to Telstra & they tested my bigpond.net.au account & advised all working So must be Thunderbird. In dealing with Telstra I changed my password. I have tried the old passwod & the new password but error message comes up log in to "Telstra account [redacted] @bigpond.net.au (POP3) failed" as I cannot receive emails can I be contacted via [redacted] or [redacted] @gmail.com Hoping this can be fixed Thanks Peter Carson Cleveland, Queensland

Yes, this outlook account was made earlier this year. I've tried all of the "fixes" offered on here and across the internet. I'm changed to to password and got the app password. I've deleted 2FA to see if that would work. I've deleted the Oauth key and it refreshed to a new one. I've done it all and TB-sync is not available to me cus apparently now i'm right outside the app version limit.... how convenient. It's very frustrating as i really like the app and still use it to read my emails but it's very annoying to have to open the outlook app and go through all that just to send an email. I keep getting told it is possible, i've been battling this on and off for months. I cant just get a new email either as i already swapped everything to the outlook one and my work using out look as well. i am able to sync my calendar even but apparently just not my outgoing emails. I would like to transfer my email but the other email i have is a proton email and they are a whole other headache. Please help.

OS: Linux / Android

TB Version: 156.0

Current Outgoing Server Setup:

Server Name: smtp-mail.outlook.com Port: 587 Connection Security: STARTTLS Auth Method: OAuth2 Username: *****@outlook.com

I reset my Windows 11 desktop OS. Now have two Trash folders in each email.

Cannot delete any Trash Folder.

Was does it do this?

Easiest way to fix this?

Hi,

I am having trouble deleting an email account in Thunderbird and hope you can help me resolve this issue.

When I click the "Delete" button, nothing happens. The "Set as Default" option is also unresponsive. I have already tried running Thunderbird as an administrator, but the problem persists.

Additionally, I tried setting up the account on my phone using QR codes, but it fails to load all my accounts. Out of 5 QR codes, Thunderbird only successfully scans 3, no matter what I try.

It seems like there might be a bug or corrupt profile data causing this, but I cannot locate the root cause. Could you please advise on how to fix this or manually remove the account?

Best regards,

Hi All,

I am on the latest release 156.0 on Windows 10. I have 3 email accounts, 2 gmail and 1 yahoo. The Yahoo account has been giving me problems since the last 2 weeks. Mind that yesterday I have a completely new Windows 10 installation so also TB installation is new.

I have renewed the Oath login, all messages were downloaded without a problem, but once in a while I get different notifications about server errors such as the ones below. There's also a third type of message error but haven't been able to get a screenshot of it.

Could someone please help me to solve this issue? I really don't understand why the problem is intermittent. Thanks in advance!

Mozilla Thunderbird installed on new WINDOWS 11 laptop in May 2026 as an email client for BT MAIL. It has continued to function without issue until early September. At which point it became an issue with sending emails difficult and mostly impossible. When sending I have been prompted to enter my account password, sometimes this would be accepted, but often not as the outgoing email would fail to be sent. The reason given that Thunderbird could not connect to the outgoing BT MAIL SMTP server, even though none of these settings had been changed since installation using IMAP. However a connection test is always a positive result and a certificate is provided. As I write today i have been able to send and/or FWD a few emails, but have no confidence that this will be the case going forward. Last week I made a one off donation to Thunderbird and after rebooting the laptop, I was able to send messages, but only for that day ! The sending issue reappeared the next day.

I have copied Thunderbird folder from C:users\maris\AppData\roaming on old PC. Had it working on the new PC, but it suffered an unrecoverable error during a windows update after only five days. Other reinstalled apps now running OK, but have been unable to replicate the successful installation from a few days ago. Found additional profiles in profiles.ini and deleted them. Made no difference!

I have been told by OZ lotteries that my emails are being soft bounced with the error "Email is not delivered because the mailbox is full or for other reasons". They suggested my email inbox is Full but that's not the case. Any suggestions as how I can fix this please?

Have recently upgraded to 156.0 and I find that the "Sent" folder in the Unified Folders shows the wrong folders. They are the same as the "Inbox" folder as you can see in the attached photo. What do I need to do to correct this?

I have a BT Internet email account configured in Thunderbird using IMAP.

I'm experiencing a problem where some emails in the message list have no Correspondent/sender or Subject, and sometimes the displayed time is incorrect.

For example, a message-list entry showed 12:55, but when I opened it, the actual email was from 8 September. The email body itself was present and correct.

My Inbox contains approximately 7,782 messages and took several days to synchronise. I also have numerous archive folders.

I have already:

Checked the BT IMAP settings — mail.btinternet.com, port 993, SSL/TLS. Allowed the entire Inbox to finish synchronising. Used Repair Folder on the Inbox. Restarted Thunderbird. Restarted Windows. Changed the message list from Cards View to Table View.

The problem persists.

Importantly, the same BT mailbox displays correctly in both the BT Mail app and iOS Mail.

I also experienced a very similar problem previously in New Outlook: some newly received BT emails appeared as [Unknown] with (No subject). Removing and re-adding the BT IMAP account and repairing/resetting New Outlook did not resolve it.

Thunderbird is therefore the second desktop IMAP client in which I've experienced this type of problem, while BT's own mail app and iOS Mail display the messages correctly.

I don't want to create a new Thunderbird profile because the existing profile contains thousands of emails and took several days to synchronise.

Could this be an IMAP synchronisation/message-header/indexing issue between Thunderbird and BT Mail?

I can provide screenshots and any Thunderbird diagnostic information you need.
