Forum zgromaźeństwa Thunderbird

Hello! Thunderbird keeps asking me for my password but it won't accept it. (My provider does accept it: the provider is BT - British Telecom.) Frequently I can't send email, when it does try to send it it takes ages: sometimes it sends, sometimes it won't. It's driving me bonkers! Can anyone help please?

Hello,

I have a MacBook Air M2, and I'm experiencing energy usage issues related to Thunderbird. This has kept happening for a long time now actually, surviving through at least two Mac OS updates, and a huge number of TB updates. Everything's up to date. I tried to follow this: https://support.mozilla.org/en-US/questions/1269944 and this: https://wiki.mozilla.org/Thunderbird:Testing:Memory_Usage_Problems?_gl=1*86dj4d*_ga*MTkzNzQ0MjA3MS4xNzYyOTY4OTMx*_ga_2VC139B3XV*czE3NjMzMTM3NDckbzIkZzAkdDE3NjMzMTM3NDckajYwJGwwJGgw but didn't succeed. Actually, in my case, the issue is more noticeable: I normally have TB open in background - sometimes everything's fine, and the battery goes down as normal, while sometimes instead the battery drops quickly, and checking in the Mac activity monitor I can see that the CPU usage of TB is totally abnormal. When this happens, I can actually see the activity bar in TB being live (bottom right corner, as it happens when TB is checking for new mails), but never disappearing. When I notice it, I just reboot TB, and the bar shuts off as normal after a quick mail check. Moreover, checking the 24hr energy usage by app, TB is often on top with nonsense values.

I tried multiple times to rebuild the database, and do most of the tricks suggested, but didn't fix. Yes I have a huge mail archive, but the problem is not the standard management of this database: basically it seems that every now and then, TB decides to run some activity which it gets stuck in, and this kills the CPU.

Thank you in advance for your help!

Good morning. I had to change my email server and the message filters aren't working. I managed to find the file where all the filters are stored and created some new ones to see the differences and try to change them, but they still don't work. I have 850 filters. Could you please help me? Thank you.

Subject says it.

Now I receive a popup asking for password, repeated after I enter the password found in Passwords. I have not altered any of the IMAP and SMTP settings.

Entries for both accounts appear correct in my authenticator.

TIA, Evan

I just installed Ubuntu 24.04.3 LTS to an old computer and I want to export my profiles and contacts from my other Windows computer Thunderbird, over to the new Linux version of Thunderbird. I suppose the other option is to re-import from Gmail contacts. Please advise. As others migrate from Windows to Linux this could be a common question.

I installed Thunderbird and Proton as per "Resist kit" Australia and New Zealand but have not been able to arrange for transfer of one Gmail account completely and process is stalled. I'm required to sign in with a password for this Gmail account but only to set it up again. Who can I speak with please?

I am using Thunderbird 140.6.0esr (64-bit) desktop on Windows 11. I have multiple email accounts setup, two of which are Yahoo accounts. On 12/21, one of the Yahoo accounts stopped delivering messages to Thunderbird from Yahoo while the other continues to download them. Thunderbird does logon to Yahoo for the account in question and gives me a message that there are no messages to download. When I logon to Yahoo mail through a browser, there is plenty of mail that has been received after 12/21 which should be downloading.

Both of the Yahoo accounts are setup exactly the same... POP Mail Server pop.mail.yahoo.com Port 995 SSL / TLS OAuth2

Outgoing server smtp.mail.yahoo.com Port 465 SSL / TLS OAuth2

I removed the password from Thunderbird for the account not delivering mail, re-entered it, restarted Thunderbird and got the same results. I changed the password (through yahoo mail), entered the new password into Thunderbird and got the same results. I also tried restarting Thunderbird again after entering the new password which made no difference.

Any help and suggestions would be greatly appreciated.

Thanks, Lew

Why suddenly has Thunderbird stopped logging my messages that I filter manually even though I have logging enabled? It used to work just fine. It no longer logs ANY message filtering. I have not changed any settings. I depend on it especially to confirm that new filters I set are working properly. How can i fix this?

For some time the feature to use color in text has not worked. I deleted and re-installed Thunderbird but no change. I cannot change the font color when typing an email, and making changes in the settings has no effect, either.

I have my "signature" saved as an HTML in color, and it also will only display in black.

Any articles and solutions posted seem to be for people using Macs or some other kind of computer. I have Windows 11 for a Lenovo Idea Pad 5. Thank you in advance for any and all guidance you can offer.

I have been trying to move my emails from an old (win10) PC to a new Win11 PC for two days now and still having problems. Can you please help with any ideas to solve my difficulty?

I have used the instructions and video on this link to the letter. https://support.mozilla.org/en-US/kb/moving-thunderbird-data-to-a-new-computer

The old PC is running win 10 pro 64-bit - thunderbird is version 146.0.1 (64-bit) My current profile is 5.3GB

The new PC is running win 11 pro 64-bit - thunderbird is version 146.0.1 (64-bit)

I have used the exact method shown in the video to copy the thunderbird folder in the roaming folder on the new PC. (C:\Users\beeni\AppData\Roaming\Thunderbird)

and then copied the thunderbird folder in the local folder as the instructions below the video in the link as I am copying profiles from win 10 to win 11. (C:\Users\beeni\AppData\Local\Thunderbird)

My username is different on the two PC's - is this important?

I'm using IMAP for new emails so only concerned about copying the emails from the local folders on the new PC.

Is there something I'm missing, can check or a method to copy the emails from the local inbox folder sections at a time to keep a zip export below 2gb?

Thank you for reading and helping

A search showed that others have experienced this same error message, but as far as I can tell, they all were unable to access their email. These messages began appearing about a month ago. They pop up in Troubleshooting Mode. They did not in Windows Safe Mode. AVG and ZoneAlarm are not the culprits.

Hello After Installing Thunderbird, and adjusted the settings to receive Outlook webmail, I have decided to stay with Outlook. Only problem is that I now receive two duplicate emails in Outlook. Please advise How I can correct this. Thank you

Recently, I have experienced an erroneous browser launch, simply by clicking on the title of the message in the list pane. This problem seems to occur when clicking on emails from a particular UK supermarket (tesco.com) and the web page opened has a long and complicated URL, but the page contains only a single pixel which shows up as a white dot on a black background.

Obviously, it is likely that there is something strange about that source, but the problem doesn't occur if I click on the same email in a different email client (in this case Evolution).

I have tried various Settings as advised by web searches and also the solutions suggested in Thunderbird Help (Troubleshooting Mode and Troubleshooting Information).

I am running Thunderbird 140.5.0esr (64-bit) on Kubuntu Linux 24.04.

Hi, my name is Rob and I have been using Thunderbird now for 3 months. Love it. There is a nagging issue. I have 2 gmail accounts. They both show events in the calendar. However one of my accounts when showing a reminder for an event, will not allow me to "Dismiss" it. Only solution is to close the dialog window. It shows the organizer as "Unknown organizer...." The other account works just fine. Any help is appreciated. Happy new year. Thx

Win 11 and Thunderbird 140 not working and I have tried all the things I found on the internet and none of them work. I have tried cleaning my registry and deleted directories and uninstalled thunderbird re-started and it will still not work.

I guess I have to forget thunderbird. It is a shame.

Hi, I setup an ubuntu 24.04 and used the default flatpak installation of thunderbird- I believe 146- via the software app, so it took a default option. Worked a few hours, then suddenly one of the 3 email accounts on outlook365 blocked sending, no messages. I tried to use some Delete "Start-Cache" option from thunderbird, and then it was no longer able to to boot, and hung up everytime. I had to delete it completely, and the user profile was gone. Not sure if an issue of Ubuntu 24.04 or of the latest Thunderbird on flatpak..I also have no error logs left, those where also deleted with the deinstallation. Ubuntu should go a version back. I meanwhile found some installation pathes for an ".deb" file and hope that will be more smooth. (I work since many years on thunderbird on my PC & Mac with no such problems ever- so this is very new) best regards, Philipp Fonberg, redacted@gmx.ch

I'm having troubles with Thunderbird version 140.6.0esr(64-bits) on Ubuntu 25.10 (fully updated). It's installed as a snap.

The first problem is that I have a selected mail with an attachment, but nowhere in the mail itself I can see or find or open or download that attachment.

The second problem is that for the inbox and mail body I can't scroll. There are no scrollbars, and the mouse-wheel doesn't work.

Is it a problem with snap? With Ubuntu? Or with Thunderbird itself? Could if be a configuration problem (I've tried quite a lot of things already)?

Can any one help please?

I help my brother inlaw with his computer, he has diminished mental capabilities when operating his PC. He has deleted his email address and its associated folders from Thunderbird and I cannot restore them for him. This is the only email address he has and does not remember the original password that was used to add the email address to Thunderbird, some years ago.
