Thunderbird Support Forum

Using the latest updated version on Windows 11. For some reason, selecting Read Receipt does not currently have any effect! P I don’t often need to use it but when I do, it’s frustrating to learn that it no longer functions. I know I can opt to make it ‘global’ but don’t really want to. All/any help gratefully received. Regards Peter

I have spent the last TWO HOURS trying to find an answer to what should be a simple problem, and it seems not to exist!

I need to find out WHERE Firebird lists my email account PASSWORD.

I do NOT want to reset my password.

I simple need to know WHAT my password is, and since I set up the account [actually a few accounts] several years ago, my notes are evidently null and void, because none of those passwords seem to work.

My email is through verizon.net, which is one of the problems because they gave all of their email coltrol to AOL, which thouroughly sucks, and they seem not to have anyone who speaks fluent English who can assist me in FINDING the current password!

If ANYONE can help, it would be most greatly appreciated!!

Since changing my email password on my BT Mail server, Thunderbird will not send emails. I get a popup saying Sending and a blue line which never completes. When I cancel it I get the following:

Sending of the message failed. Unable to authenticate to Outgoing server (SMTP) mail.btinternet.com. Please check the password and verify the 'Authentication method' in 'Account Settings | Outgoing server (SMTP)'.

There is no password change option on the Outgoing Server (SMTP). Connection Security is set to SSL/TLS and Authentication method is "Normal Password".

I can receive emails with no problems.

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

I currently receive all messages sent to me including those from Comcast but I can't send messages to any email address. When I logon i get the message: Enter Credentials for my email address on imap,comcast.net. I read the document: Switch from POP to IMAP account > Create the IMAP account. I never saw the window shown on page 3 of the document. The other day I got a message that the IMAP account was already created. I then edited the my SMTP account.

Running Thunderbird, with auto login to my ATT.NET account. I recently changed my ATT.NET PW (on ATT.NET) Thunderbird is still able to log on to my ATT.NET account and rec/send emails. I went into PW manager and removed the saved PW for my ATT email account.

Thunderbird is still able to log into ATT.NET

I have 4 e-mail accounts in TB, and I want to switch from the current default account to another. But how do I do that. I cannot see any button, place where to do that in the settings. Why the heck does TB needs to be so tricky to deal with, compared to Outlook?

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

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.
