When are you finally fixing the exponentially raising problems to work with Thunderbird and Gmail? It is getting totally out of hand! Since my upgrade to the latest version NOTHING works anymore!

After stating TB the imap.gmail.com is running forever, freezing TB up. After ending the hung up programs 5 TB processes remain. Even after trying to kill them in the taskmgr, one remains active forever, is NOT kill-able anymore, and PC needs to be rebootet. End of story!

TB become a HORRIBLE Disaster!

I have "Allow remote content in messages" turned off. However I receive many messages for which I wish to allow it for that message. I do so and it works fine.

What I would like to be able to do is to have TB learn the message senders for whom I have allowed remote content so I don't have to click it every time. Is this a feature that is available that I am missing, or is it just not possible?

If not possible, please advise as I will submit for an enhancement.

I have my gmail emails rerouted to my outlook email address and in past week my emails are not showing up in Thunderbird for a number of days after they are visable in my outlook program. Why? I have compared my Thunderbird settings with my partner and they are the same. Only difference is that my partner picks up her gmail email directly, does not use outlook and does not reroute her emails. She does not have any problems with emails arriving late to her Thunderbird inbox. We are both using same version. Any suggestions?

This is probably not a T-bird question, per se, but it is so strange it seems that this might be the best place to start, hoping someone might have some insight.

My wife and I each have our own laptops, running Win-11 Pro. Each laptop has T-bird 153.2.0esr (32-bit). We each have an account to yahoo mail (the site now hosting our Comcast email accounts). No problems since ... forever. Until today.

Now, beginning today, on my wife's laptop, when she opens T-bird, she gets a pop-up logon page, pre-loaded with her userid/email address. No input field for a password, but that it not unusual, as a lot of sites put that on a follow-up. But when we click 'next', it just rejects it. We were able to log into the yahoo mail web page (in Firefox) just fine.

After a lot of head scratching, I added her account to the T-bird configuration on my laptop. First time up, it prompted for credentials, but here it accepted them. So now we have her yahoo/comcast account configured and working just fine on my laptop, but continue to get credentials rejected running the same config on hers. Again, this has been working just fine up until today.

(If you are wondering about the connection between Comcast and Yahoo, several years ago we 'cut the cable' with Comcast, after confirming they would continue to support our email accounts. Then some time ago, they off-loaded that to Yahoo, such that we were able to retain our Comcast email address, but it redirected to and is hosted on Yahoo.)

Aloha. I'm helping a friend with setting up a new Windows 11 PC, and cannot get Thunderbird to connect to Spectrum's servers. I spent an hour on the phone with Spectrum support and they just gave up and said it must be an issue with Thunderbird. Here are the details:

- Brand new Dell 24 All-in-One EC24250 - Windows 11 25H2 plus all additional fixes. - All Dell drivers updated. - Thunderbird V155.0 64-bit

If I click on 'Get Messages' after a while I get: "Connection to server mail.twc.com timed out". I've gone into the config editor and changed mailnews.tcptimeout from 100 to 500 and still get the error.

In the Account Settings | Server Settings | Test server connection I get: An error occurred connecting to mail.twc.com:993.

I've tried this with both setting up a brand new account in Thunderbird, and also via copying the 'Thunderbird' folder from %appdata%\roaming from her old machine.

Email configuration (from Spectrum).

IMAP Settings Server name: mail.twc.com Port: 993 user name: abcd@hawaii.rr.com Connection Security: SSL/TLS Authentication method: Normal password

SMTP settings Server Name: mail.twc.com Port 587 Connection Security: STARTTLS Authentication method: Normal password

Can anyone help me troubleshoot this scenario?

I was adding some filters for senders to move emails to my local folders and such, and then I ran the filters. For whatever reason, when I ran the filters this time, thunderbird also seemingly deleted all emails from some of my web email inboxes. The only one that wasn't affected by this inbox wipe was my school email(gmail provider). How can I prevent this from happening again?

I thought I had opted for the release channel. But after a recent update, it seems I'm on the beta channel. I'm using a laptop with Ubuntu 24.04 LTS, Tbird was installed as a snap, and is updated automatically via snap. However, when I look at Help/About, the image says Beta.

The message filters simply are not working. Not only are they not directing incoming messages to the correct folders, they are also moving some messages in a folder to another folder without a rule!

I did a complete review of my message rules, cleaned them up, had some success, but the next time I opened Thundered to check email, some messages were still directed to the wrong folder. I have used Thunderbird for years, know how to use/create message rules and had no trouble prior to 155.

ALSO - tried reloading Bird 154, but it wouldn't do it because of "Profiles." Bad move there. Frankly, those multiple Profiles are a pain in the butt in Bird and Firefox, a perfect example of if ain't broke, don't fix it.

Firefox 155.0.1 Windows 10

This just started today. I am seeing question marks between the sentences in my messages. I had this issue a number of years ago and do not remember the fix. I am running the latest version on my Windows 7 desktop. It is just the new messages not the older ones in file.

Anyone remember the fix?

Thanks

Thunderbird version number: 148.0.1 Mail provider: Yahoo Client OS: Windows 10

The issue and steps I tried to resolve: On 1 Jan 2026 I switched from Outlook client on my Windows 10 PC to Thunderbird 146.0.1. I did not import any user data from Outlook but started with a clean install of TB for the new year. I use yahoo.com with POP3 as my email provider. Server Settings: Server Name "pop.mail.yahoo.com", port 995, SSL/TLS, OAuth2 Outgoing Server: Server Name "smtp.mail.yahoo.com", port 465, SSL/TLS, OAuth2

it all worked fine and I was very happy with the setup. Then from early to mid-February I was unable to use my computer. When I finally accessed Thunderbird again, it connected to Yahoo and showed that approximately 800 email messages would be downloaded and started downloading them. After downloading about 100 messages, Thunderbird timed out and I haven't been able to get it to work since.

I have read and followed or tried to follow these articles plus others that I may have forgotten about (not listed in any particular order) - OAuth2 Authentication for Yahoo, AOL and ATT | Thunderbird Help - including all the steps in Please check the following before asking for support - POP access settings and instructions for Yahoo Mail | Yahoo Help - Automatic Account Configuration | Thunderbird Help - Manual Account Configuration | Thunderbird Help - Thunderbird and Yahoo | Thunderbird Help - Send and receive messages in Thunderbird | Thunderbird Help - Can no longer get emails | Thunderbird Support Forum | Mozilla Support - Emails suddenly stopped downloading to Thunderbird 140.2.1esr | Thunderbird Support Forum - Get Messages | Thunderbird Support Forum | Mozilla Support - Cannot receive messages | Thunderbird Help - Problem with Thunderbird working with Yahoo Mail acccounts. | Thunderbird Support Forum

I have removed all messages from the Yahoo inbox and tried to find one or more messages that may be affecting the download. I don't know the best way to determine that.

I use Windows Defender for my antivirus. I don't see anything in Defender that blocks or scans email messages which would prevent downloads, although I could be wrong about that. if this might be the issue, please provide some guidance about how to check Defender.

I have uninstalled and re-installed Thunderbird. In the process I downloaded the setup file for Thunderbird Setup 148.0 and installed that version. It later auto-updated to 148.0.1. Before installation, I removed all external connections from my Yahoo account and completely removed Thunderbird from my PC, including the profile and profile.ini. When I reinstall and switch the account to POP3, Thunderbird captures the App password from Yahoo and connects just fine. But it still times out while attempting the first download of a message. The first several times it timed out, an error message was displayed but now it doesn't show anything. Except no messages are downloaded.

At this point, I don't know what else to try. Since I don't have much experience with Thunderbird, I don't know how to troubleshoot the process (logs to look at, etc.). I don't want to go back to Outlook but I need the email client to work and download messages. Any help would be much appreciated.

Suddenly two days ago all my emails began going to Spam when the download. I know of no changes to my system or Thunderbird. I deleted everything in my Spam folder and reset training, but that didn't help.

Does anyone have any ideas?

Cheers, John

I've been a Thunderbird user for years without problem. However, since May 22, three specific messages continually reappear after deleting them from my Inbox.

I keep my Inbox empty and it stays that way, except for these 3 messages. Removing them from the Trash folder has not solved the problem.

My email provider is netaddress.com via POP3 account. I signed on to look at my inbox on their site via a browser, and the messages aren't there.

I have tried repairing and compacting the inbox, but the messages continue t reappear.

Do you have any other suggestions?

TIA.

I am trying to migrate from Microsoft Outlook 2021 to Mozilla Thunderbird. I have successfully imported the email from a number of different email accounts. I would now like to import the archived emails held in a number of PST files. The import tool would seem to be what is required, but it does not seem to allow me to select the PST files that I wish to import. I am concerned that it will try to import all email messages from my Outlook 2021. Is there a way of restricting it to just individual PST files?

Our e-mail became slow, and wont open new e-mails. This has been for at least a week. A few days ago our e-mail account stopped working cokmpletely, and when prompted to sign in, it does not recognize our password. I am contacting you via a different e-mail as we have no access to hrttohrt@charter.net, which has been our primary e-mail account in thunderbird for years. What can we do?

Multiple Thunderbird Problems that started around 9/1. (Now 9/8/26) TB won’t properly download emails

   • Status bar will say “downloading 1 of 61”, pulse a while, nothing happens, then says “nothing to download”.
   • Yesterday there were no downloads 5 pm to midnight. Left on overnight in the AM there were 114 emails in box, 20 of them dated previous day 2:33 pm to 5:43 pm
   • Morning Inbox also contains 9 emails dated 8/31, which are duplicates of emails received on that date and placed in trash then.
   • It is a big business problem that I cannot rely on receiving emails in timely manner.

Many times cannot simply SEND email in TB

   • I will compose email, click send, and recently cannot expect send to be successful. Often get the message "Sending failed because connecting to Outgoing server (SMTP) failed"
   • Sometimes 5 minutes later I click SEND and the message is sent. Other times it will not send at all for hours and I am forced to use my gmail account to send an important email.

Have performed the fixes suggested online without relief

   • I have checked that the SMTP is correct. (Also sometimes SEND works)
   • Have deleted the file global-messages-db.sqlite 
   • Saved my profile, deleted the TB program, reinstalled TB, copied in my old profile.

I am in the midst of the long process of moving most (not all!) of my gmail from the gmail server to TBird, using filters as discussed in this thread.

I've started by first using filters on less important emails (ie so that no true disaster occurs if something goes horribly wrong). As I do so, I have questions!

For example, let's say I use a filter to: copy all the emails from @someone.org to a local folder then delete those emails (from the server)

What happens if one of those emails happens to be within a thread, including emails from people who don't match the filter (ie are not @someone.org). Have I broken the thread forever, ie, has something gone horribly wrong? If so, how do I prevent this behavior/have the entire thread move along with the targeted value? If not, I don't see how I can move email without breaking threads, which is a bit of a problem.

(Also - whoops, I see I should update, but the question remains.)

I have several open email tabs but they are showing nothing and when I find the email in my in box it opens blank I've also had problems with thunderbird opening have had to restart computer several times?
