Форум поддержки Thunderbird

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 have a droplet and domain at DigitalOcean. I’ve added users and I’m logging into their mail accounts with ThunderBird. I can send and receive mail between these users, but I can’t get mail from these mail accounts to Gmail and vice versa. No error. Also, when I checked the BlackList status, I saw that my droplet-IP address is in the BlackList: RATS Spam, SORBS SPAM, UCEPROTECTL3. How can I solve the problem?

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

Hi Guys, I just purchased a new Samsung S24+ and I'm trying to log into my thunderbird email account. I'm doing this through Bluemail app (suggest another if needed) and I cant remember my password! I cant seem to either change my password (which is frustrating), so cant get in. Can you please explain to me what I'm doing wrong or guide my from here? Thanks David Galea 0404841955

Trying to add https://search.yahoo.com/search?p=%s&fr=opensearch

results in an error message:

Could not add OpenSearch Provider for https://search.yahoo.com/search?p=%s&fr=opensearch.

So what am I doing wrong.

My office is running Thunderbird 115. I recently changed the password. This seemed to work OK. But on restarting TB I found the new password had not been stored. The Password Manager display is empty, so I cannot edit anything, nor can I insert a new entry into the Manager. I want to store the current password. How do I do this?

The S/MIME e-signature does not function. (The problem occurred recently.) The system can not find the certificate (the certificate is valid, it is QCA23....73.crt). How the system searches for it? What should I set in Thunderbird to find it? The openPGP functions well.

Hi, This is shared computer, so I have set up a primary password to access Thunderbird. But If I click "Anuluj" (Polish word for Cancel) - look picture TB1.png, the program still opens, asking me for a password again, but now in English (look picture TB2.png). After denying password twice, the email list shows up in the backgruond while asking for password again. If I deny the password for the third time (look picture TB3.png) I can freely browse all emails there. Any ideas on how to fix this?

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.

I'd really like the ability to whitelist a domain rather than add an email address to the address book. I work with booking websites that create unique email addresses for each booking and they keep ending up in spam. I'd like to be able to whitelist the domain they're coming from instead of trying to train the spam cannon that they are not an issue.

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

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.

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.

Dear All

I am working as DPO in a small business where they use Thunderbird as Mail client.

I have 2 questions:

1. How do I get a Data Processing Agreement with Mozilla/Thunderbird?

2. How can I make Thunderbird GDPR compliant - Tips and Tricks? I am not a computer tech or specialist, so I need down to earth solutions and we don't have a tech support within the compagny.

Thank you in advance :-)

Why has Thunderbird started to continuosly ask for the passwords for my email accounts? And why do all my attempts to enter my passwords result in failure? I am unable to send or receive any emails at the moment. If anyone is able to help I'd be very grateful.

I am using TB 115.8.1 on Ubuntu. I had set up an openPGP key for my main address but never used it. When I created templates to use for OoO as per https://support.mozilla.org/en-US/questions/1126211 I found that the OoO reply messages (even for a different address) were attaching the key. Stupidly with hindsight, I deleted the key. Now I find that many but not all the messages in my saved folder won't open as TB says, correctly, that the key is not accessible. However, I never asked TB to encrypt these messages. I also still can't get an "Autocrype: addr=" out of the replies using some of the OoO templates I created. At least for me the openPGP is pretty fundamentally broken and has lost me content and time. I like TB but this is seriously frustrating. Perhaps this is a useful warning to others.

I always thought that with a password to cancel my mailprogram access was limited to me. Now accidentally I discover that simply and repleatedly click on cancel and it will open up the program for every one to see my emails!!! What kind of use is a password if it is possible to ignore?
