I have set toolkit.legacyUserProfileCustomizations.stylesheets to TRUE in both Thunderbird and Betterbird.

I have created the file C:\Users\MYNAME\AppData\Roaming\Thunderbird\Profiles\r2v9k1zw.default\chrome\userChrome.css

I have successfully entered css into that file that work as expected in Thunderbird v115.12 and has for the past several versions. But I have NOT been able to do anything in that file that works with BetterBird. In fact, using the inspector, I don't see userChrome.css even being loaded! I have also tried starting the file with '@namespace html url(“http://www.w3.org/1999/xhtml”)' but that makes no difference either.

How do I get BetterBird to recognize the userChrome.css file?

Ever since the last update of Thunderbird, my Junk and Trash folders are empty. When I mark a message as Junk or throw something in the Trash, the messages simply disappear. I have no way of checking the Junk mailbox for messages that might be there in error. I am also unsure whether my Trash messages are being deleted permanently, or whether they are in a hidden mailbox somewhere. Please help if you can!

I was looking for an email I expected to find in my Inbox, and found that a message filter was applied to move it to another folder. I can see the filter log entry for this action.

This filter consists of 9 specific email matches ( From "is" ....); the message that was moved is NOT in this filter list.

When I moved the message back to my Inbox, it was moved again.

Any ideas on how to stop this happening? Can I even trust filters?

I recently deleted all my filters as I was not sure they were working correctly, and recreated them carefully. I currently have 10 filters, a few are one off created from a message, and none have more than 10 matching requirements.

I have attached an image of the filter at issue, and here is the filter log entry:

[7/1/2024, 9:40:07 AM] Applied filter "Bad Shopping" to message from grandrr@olypen.com - [RW] RW Potluck Tuesday July 2 at 7/1/2024, 9:19:44 AM moved message id = faecf27e13e90b655df9ff49ee14a5ec@olypen.com to imap://sjstowell1000%40gmail.com@imap.gmail.com/Good Causes & Bad Shopping

Why? Actual bug? DB problem?

I recieved emails from Microsoft to update Authentication to Oauth as support for basic authentication will soon cease. Whilst I have not been experiencing any issues, after following the instructions, also provided here:

https://support.mozilla.org/en-US/kb/microsoft-oauth-authentication-and-thunderbird-202,

I now have an unusable Thunderbird client.

This is because I am having to keep authenticating my outlook accounts (I have about ~100 email accounts). They pop up one after the other for each account.

I believe I went through all the troubleshooting steps but to no joy.

I did notice however, when the "Enter your credentials....." pop up box appears and I go through the motions of authenticating my account and TB against my Microsoft account, the following entry appears under the Settings > Saved Passwords > Saved Logins > "Provider" column for that account:

oauth://login.microsoftonline.com (https://outlook.office.com/IMAP.AccessAsUser.All https://outlook.office.com/POP.AccessAsUser.All https://outlook.office.com/SMTP.Send offline_access)

The credentials include a very long auto generated password starting similar to "M.C533_BAY.0.U.-........"

A couple of things to note now regarding the oauth entry:

1. It possibly does not always get created when re-authenticating 2. After quitting TB and then re-launching TB, it dissapears

So the solution would be to somehow ensure this entry is created and it sticks even after quitting TB, since for those accounts that include this I do not have get the "Enter your credentials....." pop up box.

Is this something TB can investigate?

Email source below -- in HTML mode the hyerlink is not being shown highlighted. Switching to Text mode it does show the hyperlink. So appears to be a bug in the HTML parser. Received: from 127.0.0.1

My many message filters were lost in updating to 115, and it has taken much time to reconstruct the new layout to be usable. If this was AI generated, it is a poor outcome.

I posted this the other day and have had no reply or I maybe cannot find the thread. Please help.

I cannot send messages from Thunderbird since it was last updated on my pc. Version 115.12.2 (32 bit). I have checked the server settings and they have not changed in years. I have been in touch with Virgin Media, my service provider, and I can send emails when logged on to my account and not involving Thunderbird. I can also send emails from my mobile phone using Gmail. The issue would seem to be with Thunderbird and this recent update. Please point me in the right direction, bearing in mind I am not particularly computer literate.

WHY is it that I can get into my email account through Thunderbird and download mail, but when I try to go into the account manually I can't? I go into the settings copy the password, then manually input it into gmail, but it says it's the wrong password? I am using MacOS 10.14.6, and Thunderbird 115.12.2 (64-bit)

Thanks.

After Thunderbird update 115.12.2(20240621154414) was installed on my PC on the 25/6/2024 I am unable to receive emails. I continue to get an error message on account noeljc@optusnet.com.au (IMAP)

   Connection to server mail.optusnet.com.au timed out.

or Failed to connect to server mail.optusnet.com.au. I have looked thru all the forums and tried various solutions without success including extending the setting for mailnews.tcptimeout to 3000. I have checked and validated my account server settings are as recommended by my ISP(Optus) are correct for authenticated emails. I even turned off my Norton VPN completely to no avail even though I use Split tunnelling to allow Thunderbird thru it as an exclusion. It appears to me there maybe a bug in the last Thunderbird update causing this. I have had this issue in the past at various times intermittently but it has always seemed to correct itself. I have been in contact with my ISP(Optus) regarding this error and all they could say was to logon to email server via webmail and did not offer any other solution. It appears there is a communication breakdown between my PC and the Email server somewhere. As I stated this only happened after the last Thunderbird update on my PC on 25/6 as it was working up until 24/6. I also have another optus email account for my wife on Thunderbird which has the same error messages. Could the Mozilla gurus please advise what to do.

I am unable to read or reply to emails. And when I close the email it shows it as still unread. I have tech support with Best Buy Geek Squad. They were unable to help, but said there was a glitch with the email program. Also is there a phone # I can call. I work from home and my email is my lifeline. Please help!

Thanks, David Lipscomb [ edited .. @bellsouth.net and phone# from public support forum]

I've had thunderbird running on my desktop for many years. I tried setting it up identically on my android and it doesn't work. I'm not sure what I'm doing wrong as I run the server side as well. How do you get thunderbird to accept no username or password for the outbound server? I'm using postfix and it only accepts outbound email from my ip address.

Microsoft sent email last night announcing the end of "Normal Password" for Hotmail, and warning that Hotmail would REQUIRE "modern authrentication" beginning 9/16. I have personal desktop subscription to Microsoft 365. I have set Microsoft account to 2FA and checked in Tbird that cookies are enabled.

I have spent hours and days trying & failing. With server imap-mail.outlook.com using OAUTH2, Thunderbird won't sync and shows message saying that server doesn't support the authentication protocol please enter another one. With 2FA still turned on and using Normal Password setting and entering an App Password from Microsoft, the Imap connection is fine about 85% of the time, needing re-entry of the App password about once a day or so (usually requires several tries until App Password gets accepted.)

The 0AUTH2 fails with Norton Smart Firewall turned Off or Turned On-makes no difference.

(Sending email with Outlook and 0AUTH2 DOES work okay.)

I've also tried Imap connection with a different server: Outlook.office365.com, using 0AUTH2.

In this case, Tbird shows me a Timeout error and never makes an Imap connection to the server.  

I've been limping along with the app password, and "normal password" authentication, but now Microsoft announces they will stop accepting connections that are not 0Auth2 ("modern authentication") from Tbird or any other software after 9/16. The clock is ticking. I've tried every remedy I've seen online from Tbird or from Microsoft. Nothing has yet allowed a QAUTH connection for Tbird to a hotmail IMAP server. Please help! !

Dear Sir or Madam,

I have just migrated Thunderbird to my new CUBI desktop running Windows 11. I get security errors when I launch Thunderbird. My email provider The Messaging Company advised me to change server settings, which are now shown in the Troubleshooting Information page as account1 (pop3) pop.themessagingco.com.au:995 SSL/TLS Normal password smtp.themessagingco.com.au:587 STARTTLS Normal password true.

On launching Thunderbird I get the message Secure connection failed live.mozillamessaging.com uses an invalid security certificate. The certificate is not trusted because the issuer certificate has expired. Error code: <a id="errorCode" title="SEC_ERROR_EXPIRED_ISSUER_CERTIFICATE">SEC_ERROR_EXPIRED_ISSUER_CERTIFICATE</a>

   This could be a problem with the server's configuration, or it could be someone trying to impersonate the server.
   If you have connected to this server successfully in the past, the error may be temporary, and you can try again later.

Or you can add an exception…

AND when I attempt to send an email I get warning that the SMTP server does not have a valid certificate. If I ask, in either case, to "Get Certificate" the response is that the site attempts to identify itself with invalid information.

I have "tried again later" over two weeks, and nothing has changed.

The Messaging Company is a fairly large email provider: it seems strange that its security is incomplete. However, I am not happy to just set an exception and over-ride these errors without doing all I can to check that there is not something screwy going on. I really value using Thunderbird, and The Messaging Company's advice that I should just use webmail is not at all satisfactory: I keep everything on my computer or backed up to a portable drive here.

Please: is there anything I can do or should know to fix this problem?

Best Regards, Margaret Mackisack
