Using Thunderbird 115.18.0esr Supernova 64-bit on Mac laptop OS 10.13.6. Worked fine for years, with ongoing Thunderbird updates, even though Mac OS is 32-bit. Suddenly, after 10/6/26 can't retrieve emails although I can see them on the ATT Yahoo server website. Can still send emails with Thunderbird. Inbound server settings are: POP server inbound.att.net, Port 995, SSL/TLS, Normal Password (I long ago created a Secure Mail Key, and even tried creating a new one). But inbound server name doesn't show in Saved Passwords (only outbound server with Secure Mail Key as password)? I have tried everything suggested, repaired my inbox folder, updated Thunderbird files, etc. in Profile as recommended. But still no prompt for password when attempting to get messages. Just shows "Done" at bottom left with no new messages received. But new messages are seen on server website. So it appears that Thunderbird isn't able to connect to the ATT Yahoo server to get emails. Why? And what else can I do? I love Thunderbird and want to continue using it.

Hello,

Is there a method to export my emails in EML format instead of Mbox without using third-party software? Are there any settings in the configuration editor that could change the default Mbox format?

Thank you

How can I get rid of that horrible bug of Thunderbird prompting me for my login credentials. Already tried the following: re-adding my Email account, reinstalling Thunderbird from scratch. Nothing has worked.

I can't get an attachment to an email message. When I select the 'attach' button, nothing happens. I recently cloned my C: drive and am concerned that something didn't get cloned properly

I'm using a mailbox.org account with TB. I'm receiving messages from it, so I'm logged in, but TB keeps asking me every so often to login again, and it has three popups in a row each time. How do I turn this off?

I use to be able to send photo's but not anymore. I have looked thru all the suggestions but can't find the answer. I am assuming that one needs to use file link, but if I choose the file link the recipient either doesn't get the email or deletes it because they now don't recognize the sender. If I ignore the file link option the recipient doesn't get the photo just the email body. What has changed in Thunderbird. I use Runbox for my main email and Gmail as alternative.

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 been through all the steps and configurations and everything is set correctly but suddenly Thunderbird does not communicate with Gmail. I have tried everything. My passwords are correct and IMAP and STMP configurations are all correctly set. Now what?

I asked this question on Google and the AI answer although sounding logical and easy did not work.

I have a number of saved emails that I would like to add to my local folders. Any help will be appreciated.

Cannot send or receive email all of sudden in Thunderbird. When I the click the messages icon, nothing happens, and I get "Could not connect to server mail.twc.com; the connection was refused". When trying to send a m,message I get "Sending of the message failed. The message could not be sent because connecting to Outgoing server (SMTP) mail.twc.com failed. The server may be unavailable or is refusing SMTP connections. Please verify that your Outgoing server (SMTP) settings are correct and try again." No settings were changed and everything was fine when I put the computer to sleep. This happens on both a Win 7 and 11 machine Email is a Time Warner (now Spectrum) Road Runner account (twc.com). Spent an hour with Spectrum, and they say this is a third party (Thunderbird) issue. A friend has the same setup, and is having the same problems that started at the same time. Win 11 version 150.02 Win 7 115.18.0 (latest available for win 7)

Appreciate any help....

I have a completely vanilla install of TB fully up to date as of this writing [it is version = 156.0.1 (aarch64) and I checked for updates], no extensions, no proxy, on a new OSX 27.0 (Golden Gate) computer and even when idling it is using substantial resources. The only thing even remotely non-basic is their is the Proton Mail Bridge to connect to Proton Mail for one of the linked email accounts, but that is its own little program with its own threads and takes almost no system resources even when sending or receiving mail (which is not happening currently.) Look at the attached screen shot.

In the screen shot I have left Thunderbird to idle for about an hour. No new mail in that time and other then clicking on or off the window to bring it to the fore I have not interacted with the program at all myself. Meanwhile Thunderbird and its Thunderbird GPU Helper are using substantial amounts of the CPU and GPU, have a combine total of 86 threads (more then any two other things running except the kernal tasks) and are hogging ram (not depicted).

Meanwhile among a few other applications (Apple Music, OfficeLibre, etc...) I also have Brave Browser opened in the background running with two windows and a total of 8 tabs wherein Brave is actively downloading GB of data from MEGA as well as performing other admittedly lighter tasks. Even when doing all this, Brave barely registers on computer resources compared to Thunderbird and Thunderbird GPU Helper when they are just idling.

Is this all proton mail's fault with the Proton Mail Bridge? If not is there anything I can do to quell the hunger for computer resources of this voracious beast of an email client that is TB and uses resources as if it were a video game even when idling?

HELP‼

Are there any •SERIOUS• “Thunderbird” savvy computer geeks in 155.0that could help me merge “old” user profile directories from *crashed* computer to a new computer without messing up either one?🙏

i used to do this stuff (with my eyes closed) but I no longer remember if I had breakfast today and they are my wife’s files! 🤬

I have new notebook computer plus the •entire• old computer data on a USB stick.

Windooze 11. TBird 152.0 installed on June 20th. Now it seems like TBird is not displaying HTML emails properly. They are displayed but not at the beginning. The first line is sometimes just the bottom half of a sentence in the email (if that makes sense). I can't scroll back to the beginning. If I go to outlook and display the same email it displays fine.

Did something change in 152.0 to cause this?

Thanks, Ed Mazurek

The list of outgoing mail servers is missing. When attempting to add a server, nothing happens after filling in all the fields and clicking the OK button.
