Thunderbird Support Forum

I am having a problem with incoming emails appearing in non-HTML format (see below), and I have checked "Allow remote content in messages" and there are no exceptions. Is there another setting that would cause the loss of HTML formatting and/or remote images? (see images of same email in full HTML and without) Thanks for any suggestions Lee

I couldn't send email, so I deleted and re-setup my email account. This lost my remembered passwords, so now I can neither receive or send email. My basic password still lets me onto TB though.

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.

Hello,

I am setting up PGP in Thunderbird. Sometimes I want to send an email which is signed but not encrypted. However, before I send this to someone else I want to make sure that it works. So I sent an email to myself (2 different accounts which I both control and have added to Thunderbird). The email has the signature attached but the Thunderbird UX doesn't give me any information about whether or not it successfully verified the signature. I tried downloading the `.eml` file and checking the signature against that, but it failed (I'm assuming that I tried to verify the wrong thing, not that the signature is actually bad).

Any help would be appreciated.

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?

I'm using Thunderbird 115.7.0 (64 bits). Cannot send messages from my email account: katy.vandenhoek@gmail.com. It says it cannot make connection to server smtp.gmail.com. Receiving emails is OK. The other emailaccounts are working OK. Looks like there is something wrong with the authentification. Reïnstalling Thunderbird didn't help.

Dear Sir

I have an issue regarding receive and sending an email from my thunderbird account. So i just take a look for SMTP server port without editing any parameter, after that i try to login the thunderbird account using mail app on my Android. But i cant login on the android then my account on thunderbird PC is error. The error said:

Sending of Username did not succed. Mail server <my mail server> responded: Protocol Error. 14

Because of that error, i cant sending or receiveng email via thunderbird. Can anyone please give your advice to solve my issue?

Thankyou...

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.

Hi

We using Thunderbird with S/MIME in order to sign email and an LDAP directory access. When we do a reply all, Thunderbird try to download recipients certificates.

It's very long and useless for us ;) (it takes more than 1 minute to the popup to disappear, or we have to click on stop searching multiple times, one for recipient)

Is there anyway to deactivate this feature ? The only way is to disable LDAP, but we need LDAP.

Thanks ! Marc

Thunderbird 115.9.0

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.

I can't Use Thunderbird with passcode. I did not understand the discussion about Comcast passcode.How do you turn on two step verification (Comcast MFA) jeraldasmith@ieee.org
