After auto update to 115.14.0 64 bit, Get Messages (from GMail) shows Inbox total rising and status shows 250 messages but no new messages appear. Each time I try to download messages the status shows the same number and totals increase by that amount. I've gone from 7000+ to almost 15000 trying various "solutions" i've found and tried. Last messages received were Sept 1st just before the update. Using GMail mail app (tremendously unacceptable) I'm able to view new messages but that app creates copious vacuum (S*KS). Background, I'm running a desktop on and currently updated Win 10 Pro with 400Gb free disk space and using No Thunderbird add-ins. As a long-time user of TB, this came as a big surprise and the only "solutions" I found even partially related were dated 4 or more years ago. These included: deleting certain profile files, disabling firewall, virus protection, and VPN. NoJoy! I'm almost to a point of backup, uninstall, re-install, and re-import but reluctant to do that because of 2 previously failed attempts to recover messages. If that is the only workable solution, please point me to an article that allows me to recover my previous message. Thanks in advance.

To whom it may concern, Not able to send emails using Windows 10 with Windows Defender as my virus and threat protection service. Attached is SMTP Server screenshot. Already tried two other recommended numbers as Port numbers and still was not able to send emails. Thanks in advance for any/all assistance. Tom

Dear community, I have recently updated my Thinkpad from kubuntu 22.04 to 24.04, which included an update of thunderbird to version 128.1.0esr (and a switch to a snap package).

However, when I type into the quick filter bar, (i) the whole thunderbird GUI freezes until the filter was applied to my several thousand emails, (ii) which also seems to take much longer than before. Before the update, the filter took maybe ~0.5 seconds or less, it now takes ~4 seconds. A lot for just a few thousand emails. Btw, the same happens if I empty the quick filter field. Just that it seems to take now even longer until it shows all of my emails.

I don't know if anyone can help. I feel more this could be something for a bug report?

Thanks a lot in advance, Matthias

Dear Community I have had an gmail account on thunderbird for years. In/outbox etc details were still on thunderbird but when checking account details in Thunderbird all info was there as normal.... but.. in "View password"..there was no details at all for this gmail account - but were there for other accounts.

Went to the gmail app and tried login...my email and password are correct...login was ok. I deleted the gmail account from thunderbird and tried to to do "New, Email Account." and entered my gmail account details correctly and hit Done when green gmail 'configuration" is "found".

Then I get a google window to sign into my gmail email account - it has correct email address shown.. I enter correct password and get this message.

"400 Thats an error... The server cannot process the request because its malformed. It should not be retried. Thats all we know"

Thunderbird email setup then shows a yellow box that says "wrong configuration... etc"

Checked in gmail settings and imap is ticked - pop is not. Also checked Gmail "Connections to third party apps and services" and Thunderbird was enabled in April 2021.

Does someone have a fix for this?? or... where have I gone wrong?? Cheers M.

I'm trying to copy the data from a PC running xubuntu 2022 onto one running Ubuntu 2024.

I'm following the instructions here (https://www.google.com/search?channel=fs&client=ubuntu-sn&q=moving+thunderbird+data+to+a+new+computer) and all seems to work up to and including "On your destination computer" step 7 (Close Thunderbird). Step 7 "From your Thunderbird profile folder in File Browser, go up two levels" - this sends me to "Common". Step 8 Right click inside the folder, then select Paste.

Here's the problem: we're not told what to click on, but I assume it's ".thunderbird", which only contains 11 items although apparently 348 were transferred. Clicking on empty space (I tried that in desperation) doesn't work. I'm probably overlooking something obvious, but I can't see what that might be. Any suggestions gratefully received. In the meantime, I will keep trying and if I somehow get it to work I'll let you folk know.

Dear all - I can't send email from Hotmail, and haven't been able to for several years now - I use the webapp, but i'd love to get Thunderbird working again...

I tried following the troubleshooting advice several times, including the most recent 2024 post, and still it won't work...

Here are my current settings, I think they're slightly different from the screenshot, but it still doesn't work!

I've checked my firewall and I don't think it's that.

I am using a VPN.

Thanks in advance, JG

A few days ago my hotmail email stopped working in Thunderbird- a box appears asking me to enter my password for ---email address--- on imap-mail.outlook.com. When I enter the password (yes, it is correct and I have logged into the webmail version) I get a second box telling me the login failed.

Last night I began getting the same messages for one of my other emails, a business email address... Login to server imap.hosts.co.uk failed and additionally now my last email address is doing the same.

I looked up the server settings and tried to check they were all ok but all appeared as it should be. I am at a loss. I went though the options in this helps section about emails but none of the options were applicable.

Any help appreciated.

Hello. I am a registered Thunderbird donor. I was using Nebula 128 with no problems on a desktop computer with Windows 10. (The computer will not allow upgrades to Windows 11). All windows updates are installed properly. After updating yesterday to Nebula 130.b03 I can no longer send emails directly from Windows desktop explorer using the send to email recipient right click function (it does nothing) or from within an Office app (Excel and Powerpoint say there is a problem with the mail client and to restart the mail client, (which I have done multiple times). Word shows a Mapi error, which I include a picture of.

From within the app, I can send and receive emails with no problems, on my different accounts, but this lack of functionality is really aggravating. I would love to be able to rollback to 128, (not sure how to do so or if it's possible, and also if it wouldn't automatically update me back to 130)... or would also have to wait and see if the next update whenever that is fixes the problem.

I have obviously restarted both the computer and Thunderbird several times, with no luck. Tried running Thunderbird in troubleshooting mode, but had the same result.

Any help will be greatly appreciated. John

Running Thunderbird 128.1.1esr (64-bit) for Linux Mint (mint-001 - 1.0) on a Linux Mint 22 Wilma system. When I click Message Filters and then Filter Log, I do not actually see the filter log, only a check box to enable it, which is already checked" - same as https://support.mozilla.org/kn/questions/1438189 I noticed it today and, as I normally check the filterlog on my primary (POP3) account about once a week, it would appear to have only started happening recently. I checked the filterlog.html files for all of my accounts - they all looked OK. Went through TB Clear Log, Close for all of them, quit TB, reload TB, same as before. filterlogs not showing. Cleared 'Enable the Filter Log', quit TB, deleted filterlogs from profiles, reload TB, enabled filterlogs, quit TB, filterlogs had been recreated in profiles by TB. Reload TB, moved some filtered mails back to inbox, ran filters again, they had been moved from inbox to deleted, showed when filterlog.html viewed in Firefox but still not showing in TB via Message Filters and Filter Log. All help greatly appreciated.

I've installed Thunderbird 128.1.1 but it stalls on startup looking for a pw for a gmail I no longer have access to. This account was deleted 6 months ago. Today, I found one item in the account list under Local Files which I deleted. The problem persists.

All of a sudden my main inbox is not showing all my mail. The other mailboxes work fine. I don't know if I accidentally changed a setting. Can someone help, please? It's my main email.

Even if a new one comes in, it disappears. Some are in my all mail, but not all.

Please help. I am waiting for mail that is very important.

Thanks in advance, Leslie

I have been using Thunderbird for IMAP email for more than a decade. I have only two folders that contain emails on the server, Inbox and Sent. All the sent emails are there going back to 2009. I periodically move Inbox emails to local folders, but the emails from 2021 to now are still on the server. I see the headers for all of them in Thunderbird, but when I click on the header of an email from between mid-2022 and a few weeks ago, the result is blank. However, when I use my provider's Control Panel to read these emails, the texts and attachments are there, and I can read them. How can I restore my ability to read these emails in Thunderbird? I am hoping there is some simple setting…

Thanks for any help.

I am unable to send or receive emails after Xfinity upgraded our package. Whenever I try to use my email, the computer keeps asking me for a new password. I would like this issue resolved. Tks, Jim :-)

Thunder bird on windows (115.10.1) freezes with a not responding message when a few delete messages are made. Earlier it used to scroll to some random location on the screen. now it freezes for a long while. Is this a bug to be fixed or something wrong at my end?

thanks Raman

Hi all,

I see lots of posts about emails disappearing but none exactly fit my situation.

I find messages disappearing especially when I move them to another folder. My config is TB115.10.1 Been using TB for countless years as an excellent app. After update 115 it has turned into a real mess for me. Always been POP accounts. Gmail is the server. All mail left on the server unless I delete it. I create a new POP account every year to keep track of emails by year. Have lots of folders to place the inbox messages.

For about a week now, when I mark as read and move a message to a folder. Say Paid" or "Cars", the message is no longer visible or selectable. I have read/unread/folder size turned on under my Inbox. So I know the missing messages are there in the folder but I cannot see them or select them. Some of the folders contents have completely disappeared. This a disaster for me. Has just started happening but was working fine before this TB update. Never happened before.

I will appreciate someones kind help.

I changed my gmail password recently so had to re-authenticate for Thunderbird.

See the attached images. When I click "next" I get the error message about JavaScript being disabled.

No idea how to troubleshoot this or what might be causing this. Help would be appreciated. Thanks

Hi, Nearly all of the User Interface windows on Thunderbird are tiny. For example, if I open the "About Thunderbird" the window is tiny. Likewise, various windows with instructions that come up are tiny. I have been able to at least read messages and read the settings windows by cranking up the font size but this does not help in general. This feels like a display resolution issue but other programs are fine. So if I change the system display res, I expect other programs to be huge. I have seen some threads on this in the archive but for older versions. I am running TB 128.1esr (I think - difficult to read!) on an iMac running Sonoma 14.6.1. I just upgraded to a new iMac and my previous installation was on Mojave and ran a thing called Theme and Font Changer, which is now disabled (possibly some buried consequence of running that add-on is resonspible). Really would appreciate help!!! Thank you. Tobias
