A hacker has messed with Thunderbird. To cover his tracks he has cloaked the contents of some folders, perhaps using threads. There are !messages but they are invisible. Any ideas?

Hello, I have recently installed an updated version of Mozilla Thunderbird as my old account kept telling me that my settings were out dated. Having installed it I am still getting the same message. Please will you advise me which settings and how do I go about updating them. Many thanks.

Can you please remove the master password Or show how to deal with this.

I have been successfully using Thunderbird (TB) with gmail for years, including via OAuth2 after gmail started requiring it. However, recently one of my gmail accounts stopped working. This seems to have happened when gmail incorrectly thought that I was attempting access from a new client or a new computer and required that OAuth2 authorization be re-established. Now any attempt to access the account from Thunderbird (receiving or sending mail) results in the OAuth2 pop-up window requesting that I allow Thunderbird to access my gmail account. I select "allow", the pop-up closes, and Thunderbird shows "Host contacted, sending login information..." but it never succeeds. After about 2 minutes, it times out with no further message. I have a second gmail account configured in the same instance of Thunderbird, and it continues to work without difficulty; for that account, gmail has not required that OAuth2 authorization be re-established. I am running TB 114.4.1 on Windows 10. I have ensured that cookies are enabled in TB and local storage of passwords in TB is disabled. In my Google account (the one that does not work in TB), I see that access for Thunderbird has been enabled.

I have tried many things, including moving my TB profile to a different folder and uninstalling/installing TB cleanly (no pre-existing profile). Attempting to set up the gmail account in the new installation fails in the same way, when trying to get OAuth2 authorization. Attempting to set up the other gmail account, which was previously working, now also fails. By moving my old profile back to its normal location and re-installing TB, I can get back to where I was (one gmail account works, the other fails).

I have access to another computer, belonging to a friend, also running Windows 10 and having TB installed. In that instance of TB, I tried creating an account tied to the gmail account that is not working in my computer. There I was able to set up OAuth2 access successfully. That TB installation is old, running version 91.7.0. I tried installing TB 91.7.0 on my computer, but there the OAuth2 authorization process still fails.

I have read RFC 6749, which describes how OAuth2 works. It says:

  "The abstract OAuth 2.0 flow illustrated in Figure 1 describes the
  interaction between the four roles and includes the following steps:
  (A)  The client requests authorization from the resource owner.  The
       authorization request can be made directly to the resource owner
       (as shown), or preferably indirectly via the authorization
       server as an intermediary.
  (B)  The client receives an authorization grant, which is a
       credential representing the resource owner's authorization,
       expressed using one of four grant types defined in this
       specification or using an extension grant type.  The
       authorization grant type depends on the method used by the
       client to request authorization and the types supported by the
       authorization server.
  (C)  The client requests an access token by authenticating with the
       authorization server and presenting the authorization grant.
  (D)  The authorization server authenticates the client and validates
       the authorization grant, and if valid, issues an access token.
  (E)  The client requests the protected resource from the resource
       server and authenticates by presenting the access token.
  (F)  The resource server validates the access token, and if valid,
       serves the request."

Apparently the failure is occurring at step (C) or (D). Either TB fails to request the token correctly, or the authorization server fails to issue the token. Step (B) succeeds; the pop-up requests my username and password, and those are accepted; if I intentionally type the wrong password, it fails.

I still have access to my mail in the problematic gmail account using gmail's web client, but I really need access via a client on my own computer, preferably TB, so that I can store messages locally and sort/access them in more flexible ways.

Please help. I've been struggling with this for many weeks, and I've spent countless hours trying to fix it.

Can anyone tell me how to blacklist incoming emails from selected addresses?

I can get T-bird to send unwanted emails to the "Junk" folder, but there are some that I would prefer not to even show up on my end, but rather delete them before they even get here (Facebook being the prime offender - hundreds of people I have never even heard of sending baby photos, etc.).

I contacted my ISP and was told that I needed to do this from the T-bird end. I cannot find anything in the Support section that addresses this problem. Thank you, Wolfgang

Unable to email GMail accounts. Error below:

Gmail requires all senders to authenticate with either SPF or DKIM

After some basic research, it was suggested that the Outgoing Server should be set to Oath2 but I am unable to change this.

This started when I received an email that spoofed my own email address and I marked it "Junk". The problem is that I send myself emails with reminders and other information that I want to access later. Now, whenever I send myself an email, it ends in Junk. I made sure my email address is in all of the address/contacts lists on Thunderbird. Every time emails from my own address end up in Junk, I use shift+J to mark them "not junk". I have done this at least a 100 times for numerous messages. I disabled junk processing, restarted, delete the junk folder, re-enable junk processing, start thunderbird again. How can I remove my own email address from the Junk filter?

I am on a new install of windows 11 (from new windows 10). I can log into Gmail on the browser(Firefox) fine. I set allowing cookis and all the other stuff I could find but I can NOT get gmail to work.

Also when I try to send an email (new message) it comes up with Newgroup where the recipient email should be

I used to be able to print my usernames and password list. I can only see it in an abbreviated form using the latest Thunderbird revision (with Microsoft). Any suggestions?

I have a new phone, and I can't get my email on it without the email password. I've had the account so long I can't remember the password; Thunderbird just retrieves my email. Now I want it on the phone. Is there a way to get my password out of thunderbird so I can put it in my phone?

We have 2 computers set up with Mozilla Thunderbird. On one of the 2, the outbound password was inadvertently changed. on the other of the 2, the outbound email works fine.

On the 1 the password was lost, I saw an option to view the password. I'd like to do that on the 1 that DOES work so I can re-enter the proper password.

Thank you,

For some idiotic reason Thunderbird is constantly creating a folder called SPAM. I want this off and never to reappear, so could someone explain how to do this. I have turned of unable adaptive junk mail and turn of the destination and retention.

This behavior is new, completely unnecessary.

Get rid of this new feature, it is not helpful

I have tried for years to get my main email address to work in thunderbird. I have 3 email accounts, two work great but my main one creber887@sbcglobal.net just keeps giving me server errors. I have no problems in firefox on yahoo. It is frustrating. It happens in windows and linux. Please help. Clark Creber

Hi, I did put a sender of a daily newsletter in the address book. I did use "Mark as Not Junk" with every newsletter of that sender in the last couple of months. . But Thunderbird always and every day lists the newsletter as Junk. (the sender is Smithsonian Magazine) So training the Junk filter does not work. How to change this failure of Thunderbird? Thanks for your attention and answer.

12-3-23 Thunderbird is asking for a second email password even though "Use primary password" is checked. This is on my Dell desktop computer running Windows 7 Professional which is the only device I use for email.

It has affected my ability to receive and send emails.

I have been using Thunderbird for years. Around the time (a few months ago) that I started getting pages of spam, I started getting the following error:

 "Login to server pop3.hughes.net with username janetc failed."

It will not accept my primary password and I see no place to find what Thunderbird is looking for in terms of another password.

Initially, when trying to block the spam, I used the process in my hughes.net webmail to block several pages of spam. However, this only tripled the amounts of spam I received. Along with troubleshooting this issue, I started marking emails as "junk" in Thunderbird. This has markedly reduced the spam.

I have tried closing Thunderbird and re-opening. Didn't help the failures.

At one point recently, I could neither receive or send emails. After my son took a look on Teamviewer, he changed some settings in my accounts to NOT automatically download emails from accounts that no longer have service. [My son is an IT professional working for UC Davis email but he doesn't use Mozilla.] After he did that, I was able to receive emails but not send.

I have tried changing some password options in Account and Server Settings.

 In Accounts settings I notice under SMTP - Edit, there are choices under authentication method  including "No authentication" and "Normal password".  Changing from Normal  password to No authentication did not help.

In Server settings, under Security Settings, there is no choice of "No authentication"

This seems to me to be a bug. I didn't make any changes in my account settings prior to this error nor prior to the arrival of all the spam.

But what did happen, which may have contributed or caused these issues is that I lost my Samsung cell phone in June of this year and did not recover it. It was password protected but I understand that it can still be accessed. I did not use that phone for email but my email address was probably given in it.

After writing all of this, I looked again in settings and found that, at the bottom of the menu list, is a second place for Outgoing Server (SMTP) settings. There I found it set to my old email address - janetc@2xtreme.net. So I changed that to hughes.net (default). I'm really confused as to why there are two places to set SMTP setting. And they can be different???? Anyway, the change did not help. I still cannot SEND.

This is the error message I get when attempting to send: "Sending of message failed. Am error occurred while sending mail. The mail server responded: Authentication is required to use this service. Please verify that your email address is correct in your account settings and try again." IT IS CORRECT!

ALSO, I can no longer find the place to change my primary password... Nevermind, I found it. I didn't realize there are two different "Settings" Menus. One is in the "pancake" in upper right corner and seems to apply to all accounts. The other is in the individual account settings. This is really confusing.

Enjoy and thank you!
