I had a Gmail address set up in Thunderbird on my old computer (Win 10). I had to get a new computer with Win 11. I have my Earthlink addresses set up okay.

But I've been unable to properly set up the Gmail address. I enter all the information, but the account vanishes from T-bird. All I have in Thunderbird is a Thunderbird Tab with Google info. It's a full page which might not come out clear with a screenshot, so I'm copying what's on this Tab ....

Google Account

   <- Mozilla Thunderbird Email has some access to your Google Account

Access you’ve given to Mozilla Thunderbird Email Mozilla Thunderbird Email has some access to info in your Google Account, including info that might be sensitive. You can always remove this access. Learn about the risks

   Access given on:  April 20, 2025
   Web address:    https://www.thunderbird.net

   Mozilla Thunderbird Email can:  Read, compost, send, and permanently delete all your email from Gmail -
   This app wants permission to do anything you can do in your Gmail, including:  (Read, compose, Add,       

ETC.)

   If you remove access 
   You might not be able to use some Mozilla Thunderbird Email features.

Another TBird Tab has: Keep track of your connection with Mozilla Thunderbird Email Mozilla Thunderbird Email has some access to your Google Account To use some Mozilla Thunderbird Email features, you gave Mozilla Thunderbird Email some access to your Google Account. This access might include sensitive info. Etc,

BUT I don't see the gmail email account itself. It had been with the other accounts, but it's not there anymore. PLEASE give me step-by-step instructions so I can access this gmail account.

I cannot seem to get Thunderbird to successfully connect to my email server on Network Solutions. Neither POP3 or IMAP works. I added an autoconfig of mail.<domain.ext>.netsolmail.net but this did not work. I am using the recommended ports and SSL/TLS settings. I can see from the Thunderbird Tools->Activity Manager that the connection is being refused. I can log into the mail account directly through the Network Solutions web access process. I used to just use a .forward on this account, but now I would like to set it up as my primary email server. Maybe there are other advanced settings on NS that need to be changed. Anyone know if there is something I am missing? I have changed the autodiscover to the autoconfig above in the CNAME and have map, mail, pop and smtp set to values recommended by NS. Do I need to add back the autodiscover setting perhaps? Many thanks for any suggestions.

I'm managing multiple email accounts in my Thunderbird installation. (Note: NOT multiple Thunderbird profiles, but things like a Gmail and an Outlook account under the same Thunderbird profile). I'm trying to remove an email account from the Account Settings menu, but clicking the red "Delete" button does nothing. I've opened up the Error Console/Developer Toolbox, and when I click the Delete button, the following error message gets logged:

``` Uncaught TypeError: can't access property "incomingServer", currentAccount is null AccountManager.js:894:18

   onRemoveAccount chrome://messenger/content/AccountManager.js:894
   oncommand chrome://messenger/content/am-main.xhtml:1

```

A screenshot of the menu is attached. Note that the "Account Name" field also stays blank for whichever account I choose, despite all of them actually having names and showing up in other locations in the application.

Greetings,

For some reason, my TB client has a conflict with my ISP provider with TB and my personal Yahoo account. When I try to authenticate my personal Yahoo account, the authentication box pops up in TB, but it points to my ISP Yahoo account with the login instead of my private Yahoo account login. I have deleted my ISP Yahoo account. Everything was fine last year; now, today, I can't authenticate my private Yahoo account in the Authentication box (screenshot below). It's not giving my personal Yahoo account security. It's giving my ISP provider login, it's Rogers.

Any clues as to why?

Regards, Marko

My work email provider, which hosts about 30 individual email accounts, returns the following when queried for quota:

a GETQUOTAROOT INBOX

QUOTAROOT INBOX Mailbox "cPanel Account" QUOTA Mailbox (STORAGE 1198939 2097152) QUOTA "cPanel Account" (STORAGE 24913212 26214400)

"Mailbox" is the individual account (at about 50% usage) here and "cPanel Account" is the whole server (at about 95%).

Thunderbird receives that data then uses the last one received for it's display (the overall server quota) which is confusing for users who expect to see their individual quota.

Is there any way I can either:

• tell Thunderbird to use the first QUOTA value ("Mailbox)
• intercept that response and strip out the "cPanel Account" entry before Thunderbird UI sees it

I can't get the response from the mail provider changed, I've already asked that.

Thanks, Dave.

Without client certificate configuration, the user can retrieve its emails on the dovecot IMAPs server using a password.

When I try to authenticate the user with an S/MIME client certificate, the dovecot server reports that: ```dovecot: imap-login: Login aborted: Connection closed (client didn't send a cert) (client_ssl_cert_missing)```

Here is the configuration: 1. On the client side: I've imported into thunderbird: - the self-signed CA certificate - the user's S/MIME client certificate which is fine: ```

1. pk12util -l user@example.com.p12

Enter password for PKCS12 file: Certificate(has private key):

``` I've setup the account to - use its certificate - use a TLS certificate as an authentication method. There is no S/MIME certificate option.

2. On the dovecot (2.4.1) server side: The server is configured to require client certificates for all IMAP connection: ``` protocol imap {

 ssl_server_ca_file = /etc/ssl/CA_CRL.pem
 ssl_server_request_client_cert = yes
 ssl_server_cert_username_field = commonName
 
 auth_ssl_require_client_cert=yes
 auth_ssl_username_from_cert = yes

} ```

Does that mean that I also have to import a TLS client certificate? If so, what format should it (.p12, .crt...) be?

Today 2/25/26 when I signed into TB, it made me authorize each email address with Yahoo..before doing so I googled and it said this was because the authorization needed to be renewed..soooo i did so for my several Yahoo-Cox accounts but now a folder that was on one account appears under another and all the email going to that account are being also sent to the other..I have checked to make sure in the tools and settings there are no forwarding indicated..any suggestions?
