Bug: signon.rememberSignons keeps resetting to false after sending an email
Status: RESOLVED
Priority: --
Resolution: WORKSFORME
Created: 2021-12-06 12:54:33+00:00
Resolved: 2022-10-06 18:21:30+00:00

Steps to reproduce:

1. Start up Thunderbird, enter master password for remembered passwords
2. Check `about:config` for `signon.rememberSignons`: set to *true*
3. Send an email (I just send it to the same account)
4. Will ask for the SMTP server password if it hasn't been saved in TB yet
5. Email is immediately sent and received
6. Check `signon.rememberSignons` again: now set to *false*
7. Toggle it back to `true`
8. Wait a while (unsure how long exactly, possibly an hour or so) or just close and reopen TB
9. Check `signon.rememberSignons` again: still set to *true*
10. Send another email from the same account
11. TB once again asks for the SMTP password
12. Check `signon.rememberSignons` again: is again set to *false*
13. Check the saved passwords list: the SMTP pass for the relevant email address is *not* in there

TB refuses to store the SMTP password, although it does so just fine for IMAP. The exact same thing happens if I do all the steps in safe mode.

I don't have any autoconfig setup (like you can do on Firefox, is that even possible for Thunderbird though?), but it only happens after sending an email anyways and that's way after when autoconfig would apply.

A strange empty context menu popup appears in the top center area of the new address book when interacting for the first time with the context menu of a list.

STR

- Open the new Address Book.
- Click on the 3 dots "more" button of an address book or list.
- Move the mouse  without clicking.

The context menu closes and that strange empty popup with chevrons appears.

Steps to reproduce:

I try to open a message in conversation view. There are messages with the replied/ answered symbol where the entry for conversation view in the context menu is missing and there are messages without any visible sign, that they belong to a conversation, where you can open the conversation view.


Actual results:

When I can open the conversation view, it displays messages that have nothing to do with the original mail. The problem started in Version 91 - I'm not sure if it still worked in 91.2, but since 91.3 it is definitely broken on my machine.


Expected results:

Conversation view should display all messages which belong to the in-reply-to message. I tried to repair all the .msf files, even deleted them and let them recreate - but the conversation seems to be held somewhere else. Couldn't find a repair/ recreate conversation entry anywhere...

Use a dark theme.
Basically everything in TB becomes dark with one notable exception: the email read window or panel.
When the email is displayed as text, there is no reason not to use the TB theme.
When the email is displayed in HTML, the theme should be used as well. Microsoft Outlook proves that dark themed emails are not only possible, but actually beautiful!


Actual results:

TB forgets it has a theme when it shows an email.


Expected results:

Use the dark theme for the emails as well.

Actual results:

I have to press either F5 or Get Messages to check for emails or wait several minutes for the automatic email check set for every 1 minute to kick in.  


Expected results:

When the application starts it should automatically check the server for any incoming emails. I never had to wait before, why do I have to wait or start refreshing the screen or hitting Get Messages now?   Efficient programming for optimum productivity reducing keystrokes should be paramount. They had it right in earlier versions and not now. Please fix this annoying issue. Thank you so very much.

Resolved: 2024-06-22 01:49:25+00:00

+++ This bug was initially created as a clone of Bug #1705824 +++

Steps to reproduce:
- Select a message in the message list which isn't the last one.
- With or without an intention of archiving, hold down "A" key a little too long.

Actual results:
- An uncontrolled number of messages gets archived.
- Chances are the user never wanted to archive multiple messages.
- User can be confused and may not know where all the messages have gone.

Expected results:
- Archiving an uncontrollable number of messages is error-prone and not really useful, so we should prevent it.

For users who want to archive multiple messages: First select the messages you want to archive (click first, shift+click last, or Ctrl+A, or some such), then press A key once to archive them.

Bug: Reconsider response to "Esc" in composition editor and tidy up

Currently, if you press "Esc" whilst focussed in the editor it will try and close the "Find in page" bar if it is visible, otherwise it will try and close the most recent notification (which is lowest on the screen).

There also seems to have been some idea to have the same behaviour in the subject input (https://searchfox.org/comm-central/rev/78e32fedfc633819cf272be3f8254c2877ea69eb/mail/components/compose/content/MsgComposeCommands.js#2857) but this is broken.

If you are focussed in the find bar, pressing "Esc" will close it.

If you are focussed in a notification, pressing "Esc" will close it if and only if it is the most recent notification. This needs fixing.

With bug 1729314 and bug 1729714 fixed, the "Find" bar and the notification elements are easier to access with the keyboard from the editor (provided the user knows about "F6" or "Ctrl+Tab"), so I wonder if we could drop the "Esc" behaviour in the editor.

In any case, the section of code needs a quick tidying up, so I'll do that first.

Once we're decided on the behaviour, we should probably add a test as well.

Expected results:

The current seen behaviour didn't happen with the previous ESR version 78.x of Thunderbird. It might be that the detection of the underlying system locale has changed for Thunderbird 91.x.

A similar misbehaviour was also happen while Thunderbird 60.x did start.

Bug: DNS Prefetch security issue: Information leak -- bug reintroduced
Status: RESOLVED
Priority: --
Resolution: INVALID
Created: 2021-12-09 14:45:15+00:00
Resolved: 2022-08-12 06:55:56+00:00

Steps to reproduce:

I used the emailprivacytester service at url: https://www.emailprivacytester.com/
On this service, I filled my actual mail address, then on Thunderbird 91.4, opened the message sent by the service.


Actual results:

The service was able to detect that I opened the message, via two especials items:
- DNS Prefetch Link (https://www.emailprivacytester.com/testDescription?test=dnsLink)
- DNS Prefetch Anchor (https://www.emailprivacytester.com/testDescription?test=dnsAnchor)


Expected results:

For a full privacy use of Thunderbird, the service should not be able to detect the opening of the email message.

This can be changed by setting 'network.dns.disablePrefetch' to 'true' in the advanced preference tab.

FYI: there was the exact same problem 12 years ago, but the bug seem reintroduced (bug 544745)
