Bug: Global password - e-mails accessible without providing a password
Status: RESOLVED
Priority: --
Resolution: DUPLICATE
Created: 2024-09-26 06:30:47+00:00
Resolved: 2024-09-26 09:14:57+00:00

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/129.0.0.0 Safari/537.36

Steps to reproduce:

I have global password set. I run thunderbird, the password prompt appears. I click cancel, the main app window appears, then Google OAuthFlow window to login to my calendars (I seems like calendar component ask the user to login and produce OAuth window because the google passkeys stored in Thunderbird are still locked under the general password), and untill I provide the general password all of that should stay hidden. 


Actual results:

Now when all canceled I can freely browse my emails on all folders and read them, print them!!! The general password prompt appears repeatedly, but I every time when I click cancel, the scenario loops and I still can work on my emails. The program freezes for a bit just after the first cancel, but after 5 seconds it is all back and I can still do some mischief on my mailbox. 


Expected results:

The app should terminate the moment I click cancel or bad password attempt. The situation is a serious security breach as I see it.
Bug: Can t access my messages after updating to 128.2.2/3 ESR - chat tab is on top

I opened a bug, Bug 1919622. The solution was to open the software in "Troubleshoot mode" and I could access again the message. 
But after updating Thunderbird to 128.2.3esr it happened again. Opening Thunderbird in "Troubleshoot mode" every time the app is updated is not really a solution.

User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:130.0) Gecko/20100101 Firefox/130.0

Steps to reproduce:

CTRL-SHIFT-F, select an entire mailbox in "Search for messages in...", enter search clue, e.g., From, blap.com, click Search button.  Note: O/S Kubuntu 24.04, H/W Intel Core i7 w/16GB


Actual results:

Status message "Searching..." appears, but the search never completes and no matches are ever displayed.  Note: this does not occur when a single folder is chosen instead of an entire mailbox.  Searching my entire mailbox worked reasonably quickly in previous versions, even though it's ~12GB.


Expected results:

Search should identify matching messages as in the past
Bug: Empty Trash on Exit not working since upgrading to 128 Nebula

Steps to reproduce:

Clicked the trash icon for IMAP messages sending them to the trash folder then exited Thunderbird by either clicking the X or by selecting File --> Exit.  If the trash folder is selected prior to exiting the trash folder is emptied.  This feature worked until upgrading from 115 to 128.



Actual results:

Messages remained in the trash folder. 


Expected results:

Trash folder should have been emptied.
Bug: Mail Message List > Message > Context Menus are missing keyboard shortcut hints (not displayed)
Status: NEW
Priority: --
Created: 2024-09-26 14:41:48+00:00
Resolved: 2024-09-27 12:09:57+00:00

As seen in TB version 131 and earlier version 115, 128, the Mail Message List > Message > Context Menus are missing keyboard shortcut hints (not displayed).

STR:

Go to Mail, Inbox, select a message, right click on selection, navigate the Context Menu and click on Mark... 

Actual result shows:

See Mark... > As Read 

Notice the **M missing**

Expected result should show instead:

Mark... > As Read **M** 

**M** being the **keyboard shortcut** to quickly mark as Read or Unread a selected Message in the Message List.

Such shortcuts are already present and accessible in in the Menu Bar menus... they somehow just did not land in the Context Menus for some reason. For this reason this bug shall be considered as defect or even a regression from Menu Bar feature disappearance (hidden by default).

It would be useful to see the keyboard hints to make keyboard shortcuts self discoverable, accessible and usable more intuitively.

Created: 2024-09-26 21:23:48+00:00
Resolved: 2024-10-14 14:20:29+00:00

Steps to reproduce:

Clicked on a given mailbox (regularly the Inbox) of a POP3 service (ie data held at 
/home/<user>/snap/thunderbird/common/.thunderbird/<user-id>.default/Mail/Local Folders/Inbox )
The messages in the mailbox vanish. 
Click on another mailbox and that is also empty and so on.
(for avoidance of doubt my Inbox has 455 messages in it and the total size of the mail infrastructure is 30GB).
_Sometimes_ closing TB, pausing and restarting restores the display. However this appears to be short lived. A more reliable restoration is to reboot the system.


Actual results:

Mailbox appears empty

Bug: Ctrl-Shift-K shortcut (for quick filter) regularly does not work
Status: RESOLVED
Priority: --
Resolution: DUPLICATE
Created: 2024-09-27 13:54:04+00:00
Resolved: 2024-09-28 13:30:09+00:00

Steps to reproduce:

I started Thunderbird, had it run for a few hours, and then hit the Ctrl-Shift-K shortcut to get the focus to the quick filter bar, to quickly find a message.


Actual results:

The shortcut sometimes does nothing, the focus stays wherever it was.

That's pretty bad because I will often immediately start typing the filter query after hitting the shortcut (the entire point of a keyboard-based UI is to allow efficient interactions like that), so if my query contains an "K" it will hide the entire thread in a way that is super hard to undo, it if contains a "J" it will mark some message as junk -- in general it's just going to cause a bunch of random havoc that can take a while to clean up, and is quite frustrating.


Expected results:

Hitting the shortcut should bring the focus into the quick filter bar.

This is not reproducible: when I restart Thunderbird, the shortcut works fine. But after some time it breaks. And then sometimes it unbreaks again. I have not yet found any pattern. It doesn't seem to matter where the focus is -- I tried focusing the folder list, the message list, or the message view; the shortcut doesn't work in any of them. Even manually focusing and then un-focusing the quick filter bar does not help.
Bug: Peer's certificate issuer not being recognized by 128.2.3esr - works for incoming, doesn't for sending (postfix)
Status: UNCONFIRMED
Priority: --
Created: 2024-09-27 15:01:01+00:00
Resolved: 2024-09-30 08:55:57+00:00

Steps to reproduce:

I have a postfix-dovecot server using Lets Encrypt certificates and a fleet of users using Mozilla Thunderbird.

For the users who are updated to 128.2.3esr, when the user attempts to send an email Thunderbird complains that the Peer's certificate issuer is not being recognized.

Only the users on 128.2.3esr are affected so far.

Dovecot is serving the same certificate for IMAP and thunderbird doesn't complain about checking email, only sending email (served by Postfix).

The same cert is used by nginx serving Roundcube, Firefox and Chrome are both happy with the certificate.

Only Thunderbird and only for sending.

We are using the "full chain" certificate and have been for years. The cert is not expired.

The only change in this environment is 128.2.3esr.


Actual results:

Mozilla Thunderbird 128.2.3esr complains about the certificate presented by Postfix for the SMTP sending of email.


Expected results:

Mozilla Thunderbird should successfully connect over TLS to the SMTP service, be happy with the certificate, and send the email.

Switching between "All" threads, "Unread" threads and "Threads with unread" doesn't work. The behaviour appears to be somewhat random. Switching from "All" to "Unread" results in an empty message pane with this console error:

Subsequently switching to something else also doesn't work:
```
An error occurred executing the cmd_viewThreadsWithUnread command: [Exception...

```

The logging is from 131.0b6, but 128 is also broken.

It already doesn't appear to work correctly in 115, but I haven't investigated this in detail.

UPDATE: 115 doesn't give a console error, but switching from "Unread" to "Threads with Unread" doesn't change the view, it still only shows "Unread", one has to go "Unread" -> "All" -> "Threads with Unread" to get the desired view.

Bug: Umlaute in the Signature Text field cause malformed emails not signable by dkim

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:130.0) Gecko/20100101 Firefox/130.0

Steps to reproduce:

In Thunderbird 128.2.3est, I entered German Umlaute in the Signature text field, see screenshot below.  

I "Compose Messages in HTML format", but the Signature text field has not activated "Use HTML".


Actual results:

emails are malformed such that opendkim cannot correctly create and sign the body hash (bh), i.e. the body is altered for some reasons


Expected results:

I presume that an ecoding problem does exist that creates an challenge for my postfix/opendkim server-setup.  Reason for my presumption is: if I set no German Umlaute in the Text Field, or if I set German Umlaute in a Signature File (Attach the signature from a file instead), the bh is correctly created and signed by postfix/opendkim
