Thunderbird Support Forum

I've installed Thunderbird on a new MacBook with macOS Monterey, and the application is not requesting permission to access the Mac's Contacts. As a result, the macOS Address Book is empty and cannot read my contacts on my Mac.

This issue was first raised two years ago in an issue that was identified as a bug and was subsequently fixed and closed. It appears this bug has reappeared.

What should happen is Thunderbird should generate a system request to ask the user to allow it to access "Contacts". This request never appears. When I look at my Mac's System Preferences, under Security & Privacy -> Contacts, there is no entry for Thunderbird. I can't manually add this; the app has to generate the request.

Looking at my console, I found the following warning when I started Thunderbird:

Refusing authorization request for service kTCCServiceAddressBook and subject Sub:{org.mozilla.thunderbird}Resp:{<TCCDProcess: identifier=org.mozilla.thunderbird, pid=9492, auid=501, euid=501, binary_path=/Applications/Thunderbird.app/Contents/MacOS/thunderbird>} without NSContactsUsageDescription key

This message was reported in the bug referenced above. I believe something has probably changed in the latest version of macOS which is causing Thunderbird to incorrectly request access to Contacts from the system.

Should I reopen the bug? Create a new bug? Please advise.

Regarding having correct settings for smtp server...After working fine for a couple of years, in May my Thunderbird email client starting getting an error when trying to send email, requiring having to wait and retry multiple times to get the email to send without getting the timeout error. I spent a lot of time in May to resolve without success, then a lot more time this month. I have tried several different settings for "Authentication method" and "Connection Security" The smtp settings specified by my email provider, WOW, either don't match the Thunderbird options, or result in error. A different set of settings I tried seem to work, as well as a variation of what a WOW rep emailed to me in May. However I wonder if either of these settings cause any security issues to be concerned about--that is my main question now, since sending email seems to be working fine again.

1) The other week I set smtp server settings to Authentication method: Normal password Connection Security: STARTTLS That has been working fine for a couple weeks without error. However since WOW says they don't support STARTTLS is that a problem to specify those settings?

2) What one WOW rep specified in May on a screen shot with a handwritten note: Authentication method: Normal password Connection Security: None However when I specify "Connection Security: None" the only option allowed for Authentication method is: "Password, transmitted insecurely." Email seems to work without error with those settings. However is "Password, transmitted insecurely" a problem? Or is that OK? (Transmitted Insecurely doesn't sound reassuring!)

In multiple calls and hours of time with my email provider, WOW, they say they don't have any information about what the settings should be for Thunderbird, and despite their efforts have not been very helpful. Attached is some information they have provided on different occasions, or from the web site. Screen shot -- Outgoing Server (SMTP) Settings Standard POP3 Server information Email Server Settings

I have the above showing on all my messages and no sender email address. It means I don't know who sent the message and I can't reply directly back. Another correspondent mentioned I needed to turn off the VPN but the link he gave me I cannot find the settings to do it.

I have been bouncing around with this daily for about two weeks, I have searched the help topics and the internet and asked every forum I know. I am nearly in tears with this!

Can anyone help me in a way that I can fix this. I am not a computer engineer so can re-write strings etc.

I have 6 gmail accounts which until last Thursday were all working fine on Thunderbird. However, I received an email for my main account from google telling me that they were switching on 2 step authentication, whether I wanted it or not.

After that imap stopped working for this 1 account. So I logged out of google for this account, and logged in again, using 2 step via phone. Still not working.

So I checked all my Imap settings with googles instructions, updated from the default smtp server, and still nothing.

Went back to google, and found I could switch off 2 step verification which I did. Thunderbird now partially works. I can download emails but when I come to send or save as draft, I get the error message as shown.

I'm using Thunderbird for gmail in IMAP mode. In my IMAP folder, I have a Junk subfolder, and in my Gmail subfolder I have a Spam subfolder. What is the difference between these? Does Gmail determine Spam, and Thunderbird determine Junk? Are BOTH Spam and Junk used for the Thunderbird adaptive junk filter log?

I followed instructions posted on a TB fourm on how to generate an app password in order for my TB to work with AOL. I'm receiving mail in Thunderbird but can't send. I suspect that I may not have followed the instructions completely and would like to start over. Do I need to delete the AOL generated password on AOL and create a new one or just create a new one for the outgoing server? Would appreciate any help! JD

Hello, I received a Yubikey 5 and all is working fine using GPG with it, except integration with Thunderbird on Windows.

I followed this guide: https://wiki.mozilla.org/Thunderbird:OpenPGP:Smartcards including 64 windows section

I was able to successfully send mail to myself, but then thunderbird failed at decrypting this message: Thunderbird is indicating that key is not available and I see no prompt from gpg-agent. Key is correctly declared as GPG external.

If I try to decrypt tis email by storing it on file and using gpg in command line, it works fine: agent is asking for Yubikey PIN and gpg is decrypting the message. But this is an awful workaround, not user friendly at all.

I also did sanity check by sending to myself a message encrypted with a key generated by Thunderbird: all is working fine, the message is decrypted within Thunderbird.

=> How do you make Thunderbird decrypt message encrypted with key stored in Yubikey? How do you make the gpg-agent called by thunderbird?

If I view an old mail, and if the remote contents are no longer available in the server, then I cannot know the contents. Whatif Thunderbird downloads the contents (when the email is downloaded) and includes them in message itself?

Gmail is going to require OAuth 2.0 sign-in SFAIK, that means I will no longer be able to access gmail with Thunderbird. Are there plans for Thunderbird to meet the OAuth 2.0 requirement?

I have been using Thunderbird for several years for my GMail accounts, and have always preferred to download my messages using the POP and SMTP protocols, rather than use the IMAP protocol which leaves them all on the web. Google now inform me that "To help keep your account secure, Google will no longer support the use of third-party apps or devices which ask you to sign in to your Google Account using only your username and password. Instead, you’ll need to sign in using Sign in with Google or other more secure technologies, like OAuth 2.0. What do you need to do? Email software, like Outlook 2016 or earlier, has less secure access to your Gmail. Switch to Office 365, Outlook 2019 or newer, or any other email software where you can sign in using Sign in with Google." These changes are due to take effect from May 30th. How can I prepare for them and still use the POP and SMTP protocols after that date? Is OAuth 2.0 appropriate?

The following Thunderbird error just started today for FOUR out of FIVE of my accounts. The error reads: "The stat command did not succeed. Error getting message number and sizes. Mail server pop.gmail.com responded. Invalid credentials." Connection Security is: SSL/TLS Authentication Method is: OAuth2 Nothing was changed in several weeks.

I saw this error was posted before but NO ONE solved the problem.

Please help.

I'm unable to add any of my Gmail accounts into Thunderbird.

When I add a Gmail account, it goes through the process of logging in via OAuth2 using the default configuration, and I get the pop-up. I enter my email address and password, and it brings me to the Google screen where I approve of giving access to Thunderbird (this screen: https://www.google.ca/search?q=google+account+permissions+screen+thudnerbird&tbm=isch&ved=2ahUKEwjtpY2M7I_3AhXHg3IEHaaPCOkQ2-cCegQIABAA&oq=google+account+permissions+screen+thudnerbird&gs_lcp=CgNpbWcQA1CVA1jjDmDED2gAcAB4AYABgwGIAbcJkgEDNi42mAEAoAEBqgELZ3dzLXdpei1pbWfAAQE&sclient=img&ei=jiFWYu2mCceHytMPpp-iyA4&bih=754&biw=1600#imgrc=ZNXSyYRJ67bY4M).

When I hit Allow, the pop-up closes, and then Thunderbird comes back with "Unable to log in at server. Probably wrong configuration, username or password."

I have no problem adding Gmail to other apps; it's only Thunderbird that is having this issue. I've already tried a fresh install on a fresh profile, but it continues to fail.

Hi there, I created a self signed certificate for use with sending and receiving emails. However, when I try to send or receive I get the following error message: "Unknown Identity" The certificate is not trusted because it hasn't been verified as issued by a trusted authority using a secure signature." When I click "Confirm Security Exception" it just hangs. On the server side the error is: fatal bad certificate. SSL alert number 42 any suggestions would be appreciated. Thanks

I've been running TB38/linux for a long time and have many extensions and .css entries. In order to comply with gmail's upcoming OAuth2 requirement, I just installed TB91 and copied over the contents of my TB38 profile into the newly-created profile.

Imagine my disgust to find that none of my .css entries (mostly involving fonts not dealt with in the preferences) and most of my extensions and colors are inoperative. I've been tweaking TB since it was Netscape .9 and appearance and LEGIBILITY (Arial bold) is really important for something that I use for many hours per day. Quite frankly, I hate this new version. If I have to I will use it in order to avoid losing my SORTED email going back to 1995, but I'll do it resentfully.

It has been my experience that with each update I lose something of value to me -- hence my stop at V38. What is the oldest version of Thunderbird/linux that will satisfy gmail's OAuth2 requirement?

I'm sure I'm not the only one wondering...

Hello!

After upgrading from a very old (but perfectly working) version of Thunderbird (24.3.0 on Windows 7) to 91.8.1 (on the same Windows 7 system), Thunderbird can no longer remember my passwords.

Apart from this everything in the new version works. Emails are retrieved fine when I enter the passwords manually.

Symptoms:

• always asks me for my passwords, even when I have checked the "Use Password Manager to remember this password" checkbox.
• no stored passwords show up in "Saved Passwords ..."
• When I try to set a primary password (I did not use one so far), I get an error "Unable to change Primary Password".

What I tried after searching for solutions:

• Remove files cert*.db and key*.db from my profile. Does not make any difference.

best regards

Edwin

Dear helpers ,

Unable to login with my password, even though same password gives me access in the webmail account.

Account provider is  : Tim. it (@alice.it)

In server setting I have :

Imap in.alice.it Port 143

Smtp out.alice.it Port 587

(On page E d i t - Preferences - Saved Passwords I only have blank page ). See enclosure below.

Many thanks to you all.

Outgoing email includes the user-agent header. I would like to disable or modify the string for better security.

User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:91.0) Gecko/20100101 Thunderbird/91.8.0

Thanks...
