Bug: try-comm-central
Status: RESOLVED

Resolution: DUPLICATE
Created: 2020-11-28 10:04:36+00:00
Resolved: 2020-11-30 02:24:46+00:00

I tried to submit a job to try-comm-central, but the job could not proceed due to

Exception: Missing package job for docker-image-debian8-base: deb8-python-psutil 

It worked a couple of days ago.

Something is wrong at least on a server where my job was handled.

But three subsequent job submissions failed by the same cause, so I suspect there is a system wide issue on try-comm-central.

Bug: Message not redrawn on content deletion
Status: UNCONFIRMED

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_6) AppleWebKit/604.1.38 (KHTML, like Gecko) Version/11.0 Safari/604.1.38

Steps to reproduce:

Type message then highlight part of the message and delete.


Actual results:

Cursor disappears, text remains highlighted and in place. 
At times the window does not responding at all for a while.
Sometimes if you start to type the new text will start to appear and will overwrite the content that was deleted. I have also seen the deleted text (still showing as highlighted) start to flash at the rate the cursor would have been blinking.

This issue has only been occurring since the latest update to Thunderbird. This issue also does not occur every time but does occur very regularly.


Expected results:

Text should be deleted, cursor should remain visible and compose window should remain fully functional

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/14.0.1 Safari/605.1.15

Steps to reproduce:

I upgraded to Thunderbird 78.5.0 (presumably from 68 something). I went through the Enigmail migration. I wrote myself an encrypted e-mail. I tried to open that e-mail after I received it.


Actual results:

As I clicked on send a message appears:
"Send Message Error"
"Sending of the message failed"

After playing around a bit I was able to send the e-mail. I had to disable signing of the message.

When I opened the message I sent I was presented another message:
"The secret key that is required to decrypt this message is not available"
The message does not decrypt.


Expected results:

Sending a signed message should have worked.

Opening the encrypted message should have worked.

All this worked before the upgrade.
Bug: Search and Filter for "To" also matches "Cc"
Status: NEW

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/87.0.4280.66 Safari/537.36

Steps to reproduce:

1. Create a temporary folder containing two messages. One message must have my email address in the "To" line. The other message must have my email address in the "Cc" line. (It doesn't matter what value is chosen for « my email address » as long as it is the same for both messages.)

2. Perform a search in that folder for « "To" "contains" my email address »

3. Perform a search in that folder for « "Cc" "contains" my email address »


Actual results:

Both messages are matched for step #2, when the search is "To" my email address. (Incorrect behaviour.)

Only one message is matched for step #3, when the search is "Cc" my email address. (Correct behaviour.)


Expected results:

Only one message should have been matched for step #2, « "To" "contains" my email address ». It should not have matched the case where my email address was found only on the "Cc" line.

This same problem occurs with Search Messages and Message Filters.

Steps to reproduce:

1. Click "≡" > "New" > "Existing Mail Account..."
2. Enter a name and e-mail address, and click "Configure manually...".
3. Ensure that the outgoing auth mode is "Autodetect" (default), and the outgoing username is not empty (default is e-mail address). Change any other settings as desired, except for those.
4. Click "Advanced config", and then click "OK".
5. Click "Outgoing Server (SMTP)" on the left, and then select the newly-created SMTP server.


Actual results:

The username for the SMTP server is empty.


Expected results:

The username for the SMTP server should be what was entered before clicking "Advanced config".
Compare this behavior to the incoming server: the entered username is transferred even if the auth mode was "Autodetect".

Bug: Thunderbird ignores "Minimized" option of Windows shortcut or command line "start /min thunderbird.exe" (no way to start minimized)
Status: NEW
Priority: P3
Created: 2020-11-29 19:47:54+00:00
Resolved: 2024-11-07 09:01:45+00:00

+++ This bug was initially created as a clone of Bug #854067 +++

Thunderbird (like Firefox, bug 585398) does not honor Windows shortcut or command line options to start up minimized. This would make a nice complement for our new option `When Thunderbird is minimized, move it to the tray`. In fact, some of the numerous duplicates of bug 208923 have requested this already.

**STR1 (see Screenshot 1):**

1.) Place a Windows link to thunderbird.exe in any folder (typically the Windows startup folder:  `C:\Users\USERNAME\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup`).
2.) Right-click on the link file > `Properties` (or `Alt`+`Enter`)
3.) Activate `Shortcut` tab
4.) Choose Run: `Minimized`, confirm with OK
5.) Double-click or press `Enter` to open the link

**STR2:**

1.) Windows-Run: cmd
2.) From command line: `start /min thunderbird.exe` (or full path to thunderbird.exe)

For comparison, perform STR1 and STR2 with "notepad.exe".

**Actual results:**

- Thunderbird does *not* start minimized for either STR1 or STR2
- (Beware of artefacts: The program might start minimized if it was already minimized last time when closed before logging off/shutting down)
- Notepad.exe does start minimized

**Expected results:**

- Thunderbird should start minimized according to Windows shortcut or command line options (regardless in which window state it was closed before).

Bug: Invalid OAuth2 settings in config for Office 365 when using Exchange Autodiscover service
Status: RESOLVED
Priority: --
Resolution: WONTFIX
Created: 2020-11-30 04:10:08+00:00
Resolved: 2024-07-03 13:23:52+00:00

When support for the Exchange Autodiscover service was [implemented](https://bugzilla.mozilla.org/show_bug.cgi?id=1500105) in Thunderbird, it produced a config with OAuth2 settings, using the URI for either OWA or EWS as the OAuth2 scope.

This is not valid for Office 365, where the required scopes are [specifically defined](https://docs.microsoft.com/en-us/exchange/client-developer/legacy-protocols/how-to-authenticate-an-imap-pop-smtp-application-by-using-oauth#get-an-access-token). For any other Exchange server, OAuth 2.0 cannot be used since the registration details (client ID, client secret, authorization endpoint, and token endpoint) are not [known](https://hg.mozilla.org/comm-central/file/tip/mailnews/base/src/OAuth2Providers.jsm) to Thunderbird; in this case, OAuth 2.0 settings should not be added here at all.

Resolved: 2021-01-06 17:53:49+00:00

The email redirect functionality in the Exchange autodiscover sequence appears to be based on either outdated or erroneous documentation, so it is checking for the wrong XML elements. Even if the XML elements were correct, the code is attempting to invoke a non-existent function, so the redirect would fail anyway.

Steps to reproduce:

Updated to 78.5.0 and rebooted the PC.


Actual results:

There are three accounts on different mail servers managed by Thunderbird.  After an update a week ago, one of the accounts quit logging in.  UI just spins wheel and on the server the login message went from user=<craig> to user=<>.  After the update yesterday (2020-11-29) and a system reboot, the other two accounts went from user=<craig> to user=<>.  

The saved usernames and passwords in Thunderbird appear correct.


Expected results:

Thunderbird uses my login credentials to authenticate and retrieve mail.

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.15; rv:83.0) Gecko/20100101 Firefox/83.0

Steps to reproduce:

Create a new message and enter a single RFC 822 email address in the composer. 


Actual results:

The "send" button remains grey even after entry of a single RFC 822 address. The valid RFC 822 address remains red.


Expected results:

--> The send button should unblock regardless of address-pill formation once a valid RFC 822 address is input. This constitutes failure to accept valid input and is at a minimum a UX fault.

An RFC 822 address must be valid input to a reasonable MUA interface. The "send" button activation should be tied to valid RFC 822 input in the composer window, *not* the internal state-representation of the pill-address. This compose-window behavior is highly discordant with RFC 822.

Bug: PGP TB78 Needs to Force user to confirm key's and encryption before sending and reading

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:78.0) Gecko/20100101 Firefox/78.0

Steps to reproduce:

Thunderbird 78.5 
SUMMARY: 
With TB68 and Enigmail installed, I would need to manually enter the password to enable Decryption of PGP emails (for 5 minutes timeframe) and for Confirmation of sending PGP emails. 

REASON: This confirmed that I and only I was the person sending and reading these emails, even if others used TB or the machine was shared.  

WHAT HAPPENS NOW:
With TB78 There is no option to confirm my password, so anyone on my TB account can send encrypted emails or read encrypted emails, if for instance my PC is stolen and the windows login password is breached (which, lets face it isn't that hard) then anyone can access my encrpyted emails on Thunderbird and send encrypted emails pretending to be me.  This is unsafe.  

Perhaps there is an option in the TB About:Config but I can't see anything that suggests such. If it does exist in the system already please advise how to activate this additional onion skin. 


Actual results:

WHAT HAPPENS NOW:
With TB78 There is no option to force confirm my password, so anyone on my TB account can send encrypted emails or read encrypted emails, if for instance my PC is stolen and the windows login password is breached (which, lets face it isn't that hard) then anyone can access my encrpyted data on Thunderbird. This is unsafe. 


Expected results:

As with Kleopatra, the encryption software supplied with Enigmail, to do any Encryption or Decryption, the password prompt is presented to ensure that the person using the machine is the person who knows the password and so only the trusted person can encrypt files. etc. etc.

Steps to reproduce:

I guess it happened after the last update of thunderbird to (78.5.0 32 bit). I didn't notice it right away.


Actual results:

I can't get new messages from the server. The program shows that it connects and then nothing happens. No mistake, nothing. As if there were no new messages. Sending new messages works, receiving does not work. By logging directly to the server, I can see that I have new messages.  I have about 10 different mailboxes on different servers in 3 different profiles and it is impossible to receive new messages on any one. (wp.pl, gmail.com, etc.). There is the same effect everywhere. The program behaves as if it is connecting, logging in and finding that there are no new messages.
