Thunderbird Support Forum

We have 2 computers set up with Mozilla Thunderbird. On one of the 2, the outbound password was inadvertently changed. on the other of the 2, the outbound email works fine.

On the 1 the password was lost, I saw an option to view the password. I'd like to do that on the 1 that DOES work so I can re-enter the proper password.

Thank you,

Every year I am required to update my university's net id password. Normally T'bird responds asking for a password update. Not this year; I am just cut off.

I followed all instructions from the T-help site. But it is impossible to update the "saved password." "edit" is not allowed.

When T-bird did ask me to connect via Google, see the screen shot, the next screen locks with a 403 error message, also attached.

I would like to continue to use Tbird, but this is making it impossible. My university's IT people had me download the T-bird again, but the problem persists.

Please advise soon.

Lately I have been getting a lot of spam and have identified all coming into my inbox as spam. Now many are automatically moved to junk mail box and that is a good thing. Unfortunately it also seems to be slowing Thunderbird down. I am afraid that many of the "Filters" generated may be duplicated. Is it possible to see them and maybe edit them to reduce the impact on my system?

I use Thunderbird on my Windows 10 desktop PC to access multiple Gmail accounts.

Since March 22nd I have been unable to send or receive email on all of my Gmail accounts. This failure started on all of my Gmail accounts simultaneously. Initially I received a popup message in the lower right portion of my screen reporting authorization failure (sorry, but I do not have the exact text of this message).

Currently I receive the following message: "Did not connect: Potential Security Issue" "Thunderbird detected a potential security threat and did not continue to accounts.google.com because the website requires a secure connection." (I get one of these messages for each Gmail account).

My troubleshooting steps so far

1) I have verified all of my passwords via the Gmail web portal. Passwords function normally. 2) My Gmail email still functions normally on my tablet and my phone. 3) I have completely uninstalled (rebooted) then re-installed Thunderbird on my PC. Failure - same message as above. 4) I have removed one of my Gmail accounts (rebooted) then reinstalled the account. Both via the Thunderbird automated tool and via manual setup (following instructions supplied by both Mozilla and Google). Failure - same message as above. 5) I have installed a different email app (BlueMail) on my PC and set up my gmail accounts. All accounts function as expected. (BlueMail sucks but at least it's functional...LOL). 6) Through the course of my trouble shooting I did receive a one time Thunderbird message indicating that Gmails security certificate had expired. (Doubtful) 7) I am running a fairly basic home network with only Windows Defender providing a software security layer. 8) I have searched through this forum (and the internet at large) for possible solutions. While the error messages I have received seem reasonably common, none of the suggested solutions have proved beneficial. 9) While not impossible, I can not associate this issue with any changes I have made with my PC hardware or software.

After retiring from the corporate world I decided that Outlook had far more complexity than I needed, so after trying out numerous email applications (both free and paid) I settled on Thunderbird which has worked flawlessly for me for over 3 years. I am currently at my wits end... hopefully someone in this forum can help. Thanks in advance, Mark H.

I am on a new install of windows 11 (from new windows 10). I can log into Gmail on the browser(Firefox) fine. I set allowing cookis and all the other stuff I could find but I can NOT get gmail to work.

Also when I try to send an email (new message) it comes up with Newgroup where the recipient email should be

Yesterday I set up a new password. Then said sending a code. Cannot get the code as I can not get messages or send out messages on your site. My other device is my phone to get a code. I am only in your site as I kept clicking the screen several times and you popped up. Forgot my original password. I am getting your messages on Spectrum Webmail. At the end of January I could not sent out an email; then could not receive an email. Was working fine up to then. Do not know what happened. Just want to get back on Thunderbird as I have important folders and my contacts.

Hi All,

Not really have no clue what's happening, I think I've by accident put some kind of rule on. It's only with one organization whenever they send me an email I see it coming in but in a blink of an eye it's gone. I've looked everywhere what could be the problem but can't find it. Even when I search on the subject in my inbox, Thunderbird shows me it found emails but doesn't show when any, only the count of the emails.

When I check the mails do stay in my web-based Outlook, via "Owl for Exchange" I get my mails in Thunderbird, no other emails have this problem.

Anyone who could point me in the right direction would be much appreciated.

Many thanks! ~Muriel

Dear sir, madam, I have a Thunderbird account. I have access to it and to the menu, but I have to put a password in to receive my new emails. I don't know my password and have tried really everything that is suggested on your website to get my password, renew it, access a reboot-option etc: nothing works - I still keep getting a window where I am asked to put in the password for my account. Please help me fix this, thank you in advance, greetings, M vd vegt

I do not understand how to set Thunderbird for Comcast's two step passcode. How do I get the passcode, My bank sends a passcode by landline for checking and email for credit card.

Sorry in advance for the long reading.

For my personal needs I'm currently using the general purpose desktop platform UBUNTU 22.04.04 LTS and GNOME/WAYLAND. Thunderbird is my personal e-mail and productivity client application, now in it's stable version 115.8.1 (64 bits).

For many years I used to sign my personal emails using S/MIME and a high assurance (Qualified) X.509 digital certificate, protected by my personal ID card (i.e. a smartcard), which is provided by my government (Belgium). It used to work flawlessly under Xubuntu, my favorite OS flavor until about a year ago, with earlier versions of Thunderbird.

Since I migrated to UBUNTU's standard flavour (using WAYLAND), it doesn't work any longer.

I experienced the same behaviour with Firefox when Canonical started distributing only the SNAP version of the app for Ubuntu. This problem is well known and documented. I applied the recommended solution, which was - and still is - to install the Mozilla binary version along the snap version. I can since happily continue authenticating and connecting securely to any belgian e-government web site using the Mozilla firefox binary version with my certificates/Id card, while using the snap version for other purposes.

So I tried the same recipe with Thunderbird, ... to no avail. Both versions (Ubuntu-snap and Mozilla-binary version 115.8.1) display the same, consistent behaviour. I must precise here that I can load the BELPIC PKCS#11 subsytem and configure Thunderbird like I always did. After asking for my smartcard's PIN, TB can access the smartcard and lets me associate my certificate with my email account. Everything seems to work as usual until there, except that signing a message does not work. TB systematically displays the same error message "... the application does not find the certificate or the certificate has expired". Of course my certificate is not expired. It looks like the message composer (not Thunderbird itself) cannot access the smartcard. Disabling apparmor leads to the same result with both the snap and Mozilla versions of TB.

Still, TB - both versions - works as expected when using low-assurance digital certificates, e.g. issued by CAcert.org. I also use those for receiving encrypted personal messages when needed. But those are stored locally together with their private keys.

There is no interest in signing messages with a digital certificate without any legal value, especially on a system that is meant to be more secure. I migrated to the standard ubuntu desktop for the added security provided by snap, apparmor, Wayland, ...

Before I file in a bug record, would someone be in a position to provide any useful hint?

Many thanks in advance.

Hello,

I am getting a failed mailed delivery message every time I send an email.

The error reads:

host submission.antispam.mailspamprotection.com [34.111.121.216] SMTP error from remote mail server after end of data; 550 high probability of spam 1rITD-006zLY-2v

Reporting-MTA: dns; es81siteground.eu

Hello hi ya' doin',

I'm running Thunderbird 115.7.0 IMAP on a laptop with Win10Home. I also have an iPhone and iPad.

Normally when I open Thunderbird on the laptop it asks for my password, even before I check/send mail. A few days ago it stopped asking for the password, and will check for mail without asking for the password. Sending mail still asks for the password. Mail sends/receives on all devices and on webmail.

How do I get Thunderbird to prompt me for my password when I open the program, or at least before I check for mail?

I'm having trouble with my Thunderbird password. I have 2 emails with identical settings and passwords. One works fine. The other's asking me for my password. When I enter what I knew for certain was the password I get the message, "Login to server imap.comcast.net with username weissfamily@comcast.net failed." I successfully changed the password still get the same error message. Also I get a Thunderbird popup that says, "Alert from account weissfamily@comcast.net: 1014." This is all above my pay grade. Need assistance. TIA. Tim Weiss

I still need help with passcode. I sent a response about my first question passcode. Your webpage is very complicated and I do not understand it. I can't get to the last thing I did very easily. Currently I have remember my device turned on so no passcode is sent when I log on. I don't know how to turn it off. I have been working about a week on this problem. I think one message said you needed to input passcode when you are asked for password. I also do not understand how to change the password when asked for new password. Also, I have not been giving donations to Thunderbird because they only appear to accept credit cards.

My Gmail account opens fine in Chrome. Thunderbird can't get to it; it says my password is incorrect. I have tried it enough times to know I've not typed them all incorrectly.

I'm baffled, all help gratefully received.
