Bug: IMAP Attachment Download Failing if attachment > 20MB
Status: UNCONFIRMED
Priority: --
Created: 2021-08-27 21:38:59+00:00
Resolved: 2022-07-14 20:21:18+00:00

User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:91.0) Gecko/20100101 Firefox/91.0

Steps to reproduce:

Configure for IMAP.  Uncheck Message Synchronizing in Synchronization & Storage.


Actual results:

When receiving a message with an attachment of size of approximately 20mb or larger and attempting to save, the following is observed:
-Message at the bottom says downloading and never goes away
-In the folder (on the OS) selected for download, size remains at 1k for attachment selected for download.


Expected results:

Attachments should download regardless of size.
Bug: Unable to send messages (using gmail smtp)

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:91.0) Gecko/20100101 Firefox/91.0

Steps to reproduce:

Compose new email, click the send button.


Actual results:

Email address is ok, the send button is not greyed out, click send button, nothing seems to happen.  Click File, Send later, nothing happens, nothing down the bottom of the window indicating that it's trying to communicate etc.  I setup a password with Google, Thunderbird asks me to update password for IMAP, and it's saved in options, but at no stage will it ask for a new password for SMTP.  It's like it's not trying to communicate with the SMTP server, but it doesn't complain that it can't communicate with the SMTP server either.


Expected results:

Ask for SMTP password, send messages.

The "Languages" tab has a link to ATN. In 91.0.3, this link opens in an external browser, it should open in Thunderbird.

I checked Daily but it seems like this tab doesn't appear there by default and I don't think there are language packs for Daily so not sure how to make it appear for testing purposes.
Bug: browserAction.setIcon() throws "IconPath not found" error
Status: RESOLVED

Resolution: DUPLICATE
Created: 2021-08-28 20:19:11+00:00
Resolved: 2021-08-29 11:07:45+00:00

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:91.0) Gecko/20100101 Firefox/91.0

Steps to reproduce:

This is a simplified version of the code I'm using to change the button icon when a button is clicked:

browser.browserAction.onClicked.addListener(() => {
  const icon = 'icons/heart-outline.svg'

  browser.browserAction.setIcon({ path: { '16': icon, '32': icon } })
})

Note that "icon" is a relative path.


Actual results:

In v78, when I clicked on my browserAction button, my button would also change its icon.

In v91, I get the following error:

It doesn't appear that browserAction.setIcon has changed since v78.
Bug: Subject field text disabled after saving message (DE)

User Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:91.0) Gecko/20100101 Firefox/91.0

Steps to reproduce:

[TB version 91.0.3]
- open message compose window (new email)
- enter some text in 'Subject' line
- save message (Ctrl + S)


Actual results:

The text/content entered in 'Subject' line becomes greyed out and cannot be edited any longer. Unless message compose window for that particular message is closed and re-opened.


Expected results:

Editing text in 'Subject' line should be possible even after saving message /pressing Ctrl + S - without having to close and re-open the message saved in draft.
Bug: SendMessageWithCheck fails to check whether nsIMsgCompDeliverMode.Background is actually available
Status: UNCONFIRMED
Priority: --
Created: 2021-08-29 15:43:59+00:00

User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:91.0) Gecko/20100101 Firefox/91.0

Steps to reproduce:

I'm not positive if this is a bug, but I just noticed that the functions `SendMessage()` and `SendMessageWithCheck` in MsgComposeCommands.js differ slightly in one of the parts where I'd expect them to be identical.


Actual results:

SendMessage() does the following:

```
  let sendInBackground = Services.prefs.getBoolPref(
    "mailnews.sendInBackground"
  );
  if (sendInBackground && AppConstants.platform != "macosx") {
    let count = [...Services.wm.getEnumerator(null)].length;
    if (count == 1) {
      sendInBackground = false;
    }
  }
```

but SendMessageWithCheck() does not implement the second conditional.


Expected results:

Maybe there is a reason that I'm not aware of, but the asymmetry made me think something might be up.
Bug: change font size, in the German version for quite some time,current installed version 78.13.0 (64-bit)

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:91.0) Gecko/20100101 Firefox/91.0

Steps to reproduce:

I enter text myself, or copy it into the text field.
Now I would like to adjust or unify the font size.



Actual results:

If I select a larger text field and then change the font size / unify often nothing happens. In small areas (wordwise) it works most of the time, However, this happens mostly when mixing self-entered font and inserted font fields.


Expected results:

I think it shouldn't matter that there can be different fonts and font sizes in the selected text fields to be adjusted in order to match them. Unfortunately, this does not work at least for me. Mails with self entered text is usually no problem. However, if you mix this with copy and paste text parts, this usually does not work.

Bug: accessibility regression: Account settings tree item names are messed up
Status: RESOLVED
Priority: --
Resolution: INVALID
Created: 2021-08-30 10:35:00+00:00
Resolved: 2021-09-02 13:43:44+00:00

As of TB 93 (latest nightlies), the Account Settings tab’s left panel has  
evolved from a GTK tree into a list box. As a result, the tree is messed up  
and specifically the top-level items (e.g. the account names and the  
“Local Folders” parent category). That’s an accessibility regression.

Launch TB, open Account Settings and browse the AT-SPI tree (either with  
Orca, Accerciser or directly with pyatspi). Here’s what you used to get:
```
[document web | name="Account Settings"]
-- [tree | id="accounttree" ]
-- -- [list]
-- -- -- [tree item | name="foo@foo.bar"]
-- -- -- [tree item | name="Local Folders"]
```
Here’s what you’ll get in the new panel:
```
[document web | name="Account Settings"]
-- [list box | ]
-- -- [list item | name="foo@foo.bar Server Settings Copies & Folders Composition & Addressing Junk Settings Synchronization & Storage End-To-End Encryption Return Receipts"]
-- -- [list item | name="Local Folders Junk Settings Disk Space"]
```

This appears to have been introduced very recently (in the past couple of weeks at most).
Bug: Since I installed the latest release on August 11, Tbird does not delete incoming mail messages from the POP3 server when it fetches mail.
Status: RESOLVED

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:91.0) Gecko/20100101 Firefox/91.0

Steps to reproduce:

Opened Tbird as usual, new mail is fetched from the outlook POP3 server, and the server shows the fetched message as being read.  Tbird settings are configured to also delete it from the server.  These settings have not been changed by me; the only change was to update Tbird to this version on 8/11/21.


Actual results:

Outlook POP3 server did not delete the fetched emails, but it did mark them as read.  


Expected results:

The emails should have been deleted from the Pop3 server.   I searched for this issue on MS sites as well, nothing found.

Bug: F6 jump focus handler is inconsistent for the message tab
Status: NEW
Priority: --
Created: 2021-08-31 10:10:59+00:00
Resolved: 2022-09-11 01:45:04+00:00

### Steps to Reproduce

1. Launch Thunderbird.
2. Either do nothing and keep the focus on the initial `tabmail-tab`, or move focus to the top `#tabs-toolbar`, the toolbar `#mail-bar3`, the `#folderPaneHeader`, or the Today pane `#agenda-panel`.
3. Press F6 twice.
4. Tab incrementally into the Folder tree, or select with mouse to focus it.
5. Press F6 three times.

### Result

In step 3, focus moves between the main `tabmail-tab` and the `messagepane`.
In step 5, focus moves between the `#folderTree`, `#threadTree` and `#messagepane`.

Note, similar things happen when pressing Shift+F6, which just reverses the direction.

### Expect

The behaviour should be more consistent:

+ The `#folderPaneHeader` should be treated as the same area as `#folderTree`, so pressing F6 in either place should move the focus in the same way.
+ The behaviour of pressing F6 from the `#messagepane` shouldn't depend on how the area was entered.

## Possible Solution

My idea would be to section the main areas of the message area as:

1. The tabs.
2. The toolbar (or merge into the same area as the tabs).
3. The folder area (`#folderPaneHeader` and `#folderTree`) if visible.
4. The thread tree.
5. The message display if visible.
6. The Today Pane if visible.
7. The status bar if visible (which currently does not recive focus through normal tabbing)

And F6 should cycle through these in this order all the time. If some areas should be excluded from this list, then F6 should do nothing when within those areas.

The function to fix would be `SwitchPaneFocus`.

This is a follow-up to [#1728087](https://bugzilla.mozilla.org/show_bug.cgi?id=1728087).

I found something even better (by which I mean worse):
- Open the Account Settings tab.
- Check the list box on the left (it opens on your Local Folders or on your email account by default).
- Hit Tab a bunch of times until you reach the “Account Name” field on the right.
- Hit Tab just once more to move on to the next item.
- In the list on the left, your account name has now become blank. The item’s still there, it just no longer has any name.

(Actually if you reach it, at-spi will still have the oh-so-palatable name “Server Settings Copies & Folders Composition & Addressing Junk Settings Synchronization & Storage End-To-End Encryption Return Receipts”, but that appears to be a side effect of #1728087. None of that is displayed anyway.)

Bug 1711274 ported extensionControlled.js from mozilla-central into comm-central, but it has a few problems:

+ It contains dictionary objects (https://searchfox.org/comm-central/rev/2b9757e10d3304dbb539a4b3fdded6699db54b20/mail/components/preferences/extensionControlled.js#58-79), but I think only the `proxy.settings` entry is actually used. The unused entries should be removed. If there is only one used entry, some of the methods that use these dictionaries could be made specific to this setting, which would make the code less convoluted.
+ `initListenersForPrefChange` is defined but unused. It should be removed.
+ We are missing fluent entries for at least `extension-controlled-proxy-config` and `extension-controlled-enable`.
+ We are missing the image source `"chrome://browser/skin/menu.svg"`.
+ `showEnableExtensionMessage` uses xul elements in a semantically incorrect way (e.g., a xul:image is used as a close button, and a `xul:label` is used to display a message). We should probably change this to html as well. Note: this is inherited from mozilla-central.
+ There are `html:img` elements with no `alt` attribute, or some accessible name. Note: this is also inherited from mozilla-central.

Side note: there are elements with a `title` attribute, but no `alt`. If an `img` must have a `title`, then it is usually preferable to leave the `alt` attribute unset, rather than set to `""`. This is because the accessibility tree will use the `title` as the accessible name, whilst the technical specification would mean that `<img alt="" title="helpful name" />` would actually be ignored. Note that firefox does not currently follow this technical specification, see Bug 1700174, but we should still try to avoid it.

The main window has [one implementation](https://searchfox.org/comm-central/rev/2b9757e10d3304dbb539a4b3fdded6699db54b20/mail/base/content/mailWindow.js#51) of gUIDensity, which updates other windows, and I'm about to add another implementation in bug 1727872 because the Address Book tab doesn't get updated automatically.

Apart from the obvious duplication problem, the main window object would add a new observer for every main window that opens, and each of them would try to update all other windows. We should centralise it all somewhere in a JSM so only one observer is needed, and either figure out how to update all windows and tabs automatically, or provide a way to register for updates (like `colorTracker` in calViewUtils.jsm).
Bug: TB 91.0.3 crashes with Owl and an Exchange account

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:91.0) Gecko/20100101 Firefox/91.0

Steps to reproduce:

1. Install Owl.
2. Set up a Microsoft Online account
3. Configure the account in Thunderbird.
4. Restarted Thunderbird.

I also retried step 4 with all other extensions disabled.


Actual results:

When TB starts, a tab is opened which seems to access some webpage (?) ... but before it's done, or perhaps right when it's done - which happens within a second or so - Thunderbird crashes.

No crash.
