Bug: Wrong parsing of quoted display names with angle brackets when replying: |"John Doe <UX>" <john@foo.bar>| truncated to |John Doe <UX>|
Status: NEW
Priority: --

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:75.0) Gecko/20100101 Firefox/75.0

Steps to reproduce:

senders email contains:
From: "A B <C>" <d@e.f>
i.e. angled brackets in the display name. My University and its Outlook server adds departmental names in angled brackets to the sender's name (here: <C>).
When replying (ctrl-R), all quotation marks are stripped, making it 
A B <C> <d@e.f>
in the "To" field.
There are now two sets of angled brackets; the first is parsed as the send-to address, causing problems.


Actual results:

When sending this reply the first angled bracket is interpreted as the email address and hence an error is returned that it is malformed (of course it is).


Expected results:

Admittedly  this is a strange use case, but is a result of the outlook server configuration. I am not aware that this has been a poblem in older versions, but do not know exactly when it started.
Two possible solutions:
1) The original enclosing quoation marks are not removed.
2) When encountering more than one pairs of angled brackets, the last one is used for the email.
Bug: Cannot delete a Customized Header

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:60.0) Gecko/20100101 Firefox/60.0 SeaMonkey/2.57

Steps to reproduce:

I have three GMail IMAP accounts. I was troubleshooting an issue as to why the option for searching "Body" had disappeared from Classic Search on my default GMail IMAP accounts. I attempted to manually add "Body" back using the "Customize..." option thinking I had accidentally deleted it.


Actual results:

When I added "Body" back, it did not work as expected so I tried to remove it. I was not able to remove it after creating it. The only way I was able to remove it was to reset mailnews.customHeaders to default.


Expected results:

If you create a new Customized Header, you should simply be able to highlight it and click remove and it should be removed or deleted properly without needing to edit or reset mailnews.customHeaders

This is happening on Thunderbird Daily 77.0a1.

I cannot configure a new Yahoo or Gmail account in Thunderbird.

Steps to  reproduce:
- Start with a fresh install of Thunderbird.
- In the Account Wizard, configure a n new Gmail or Yahoo mail account. Go through OAuth the login process and grant Thunderbird the permissions requested.
- Return to the Account Setup  dialog, note that the "Done" button is disabled.

Troubleshooting:
- Tried Manual Config and Advanced setup. Error dialog pops up in both cases: "Incoming server already exists"
- No IMAP account is displayed in the Account Settings panel, but there is an SMTP account that appears to be complete.
- about:config contains IMAP settings

The email signature of A is plain text.
The email signature of B is HTML.

1) I want to send a new email. In my accounts list, account B is highlighted (marked blue). I click on "new email". A window opens and I can see the working HTML signature. Everything is fine.

2) I want to send a new email. In my accounts list, account A is highlighted (marked blue). I click on "new email". A window opens and I can see the working plain text signature. Everything is fine.

3) I want to send a new email. In my accounts list, account A is highlighted (marked blue). I click on "new email". A window opens and I can see the working plain text signature. So far so good.
But now, I change the sender adresss/account in the dropdown list from A to B.


Actual results:

The email signature changed from A to B. But the signature kept as plain text.


Expected results:

I expected a change from the plain text signature to a HTML signature.
I did not test, if the whole email is not sendend as HTML.

Bug: high load after short time in background (linux)
Status: RESOLVED
Priority: --
Resolution: WORKSFORME
Created: 2020-04-24 16:28:41+00:00
Resolved: 2020-12-30 15:50:46+00:00

User Agent: Mozilla/5.0 (X11; Linux i686 on x86_64; rv:68.0) Gecko/20100101 Firefox/68.0

Steps to reproduce:

1. create a new profile
2. cancel eMail-account-creation
3. bring some other windows to front, so the main-window isn't visible any more
4. wait some time (4..5min)

system is a core i7 with 32G RAM with linuxmint19, thunderbird is 68.7.0 32bit german (de) from ftp.mozilla.org-releases-tree.

with a normal profile and some addons the time to wait in (4) will be reduced.


Actual results:

thunderbirds load goes up from 0% to 150% 

sometimes this stops after some time, but then starts again a bit later.

(and the noise of the cooling due to the permanent load is really nasty)

a (separately executed) strace shows, that there's a ping-pong within an unnamed pipe (last test from fd53 to fd52), where a single byte 0372 / 0xfa is transfered all the time from a thread to the main-process. This transfer also occures on low load sometimes, but on high load it seems to loop. Maybe this is a symptom only, but not the reason for the load, but perhaps it helps to determine the reason.

a whole cycle (which loops on high load) is like this:
```
[pid 14284] futex(0xf7821d04, FUTEX_WAKE_PRIVATE, 1) = 0
[pid 14220] <... futex resumed> )       = 0
[pid 14284] write(53, "\372", 1)        = 1
[pid 14220] recvmsg(4,  <unfinished ...>
[pid 14284] futex(0xf7821d48, FUTEX_WAIT_PRIVATE, 0, {tv_sec=0, tv_nsec=95357529} <unfinished ...>
[pid 14220] <... recvmsg resumed> {msg_namelen=0}, 0) = -1 EAGAIN (Resource temporarily unavailable)
[pid 14220] poll([{fd=4, events=POLLIN}, {fd=5, events=POLLIN}, {fd=8, events=POLLIN}, {fd=52, events=POLLIN}], 4, 0) = 1 ([{fd=52, revents=POLLIN}])
[pid 14220] read(52, "\372", 1)         = 1
[pid 14220] recvmsg(4, {msg_namelen=0}, 0) = -1 EAGAIN (Resource temporarily unavailable)
[pid 14220] poll([{fd=4, events=POLLIN}, {fd=5, events=POLLIN}, {fd=8, events=POLLIN}, {fd=52, events=POLLIN}], 4, 0) = 0 (Timeout)
[pid 14220] futex(0xf7821d48, FUTEX_WAKE_PRIVATE, 1 <unfinished ...>
[pid 14284] <... futex resumed> )       = 0
[pid 14220] <... futex resumed> )       = 1
[pid 14284] futex(0xf7821d04, FUTEX_WAIT_PRIVATE, 2, NULL <unfinished ...>
[pid 14220] futex(0xf7821d04, FUTEX_WAKE_PRIVATE, 1 <unfinished ...>
[pid 14284] <... futex resumed> )       = -1 EAGAIN (Resource temporarily unavailable)
[pid 14220] <... futex resumed> )       = 0
```
and then repeats...




Expected results:

thunderbird should keep idle the whole time

    if (!matchRequest(channel, this.filters)) {

I have no idea why stack-trace-collector.js tries to use websocket channel.
But if it needs to access something from the net to provide stack trace(?) and
fails due to the net access issue because of missing interface, we are in trouble.
We can't have a reasonable stack trace in case of a serious error?

forgot about the opened console when I realized these error lines.

Bug: Lightning/Calendar bug on "find events" for events that "repeat"

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:68.0) Gecko/20100101 Firefox/68.0

Steps to reproduce:

This is a very, very old bug present in all versions of Lightning/Calendar Extension, that affects the "find event" search mechanism.


To replicate the bug:

1. Create an event title "MY EVENT THAT REPEATS" set for 10/10/2015 that "repeats" monthly until 10/10/2030.

2. Press "Find Events" button. A search panel opens.

3. In such panel, set the search to "All Events" in the pull down menu

4. Fill the search box with MY EVENT THAT REPEATS

5. In the panel result area is shown one single entry of MY EVENT THAT REPEATS with the date of 10/10/2015. That is the first problem: it does not shown all monthly entries until 2030, but one single entry.

6. Change the search to "All Future Events" in the pull down menu. Second problem: no entry is shown! Where are the monthly entries until year 2030?




Actual results:

Search panel does not show all recurrences for events that repeat, but only the first entry of such event is searchable.


Expected results:

Should show a list of all (monthly) entries from 2015 to 2030.

During the last couple of months, it happens more and more often that thunderbird freezes keyboard of whole sesssion (i.e. while this happens, it's not possible to type anything in any application on screen). Usually, violently jiggling the mouse fixes the issue, but it is still annoying. And sometimes it can have very weird/annoying side effects

Recently, this happened as I was composing a reply to a mail message. Midway through, I wanted to look up some detail that I needed for my reply in a PDF file. As happened so often, keystrokes were ignored when trying to launch okular. Jiggling the mouse fixed the issue, but when I came back to thunderbird, I saw something very surprising: the message that I was replying to had a "no-parking sign" next to it (with white background rather than blue), and after I had restarted thunderbird, the message was no longer shown. Fortunately, the draft reply I was composing was still there. Oddly enough, the message was also still in my inbox file on the server.

N.B. The keyboard freeze issues seem to be shared by all Mozilla Foundation applications, also Firefox. Also in Firefox I haven't seen any weird side effects so far... So I suspect the culprit might be some common library used by both.

Actual results:

You can introduce the IMAP server either way, but when it is settled the program does not recognize the path of the server. I think it because it does not recognize long paths. My server is smtp.unavarra.es and imap.unavarra.es and instead, it uses tp.unavarra.es and map.unavarra.es when redirecting to server folders (i.e. imap://gustavo.marcos@map.unavarra.es/INBOX, shortening the "i"). It happened to me for several latest versions.

Steps to reproduce:

Compose a message. My default is to compose plain text, and I use 'variable width, size medium' font. My default is Calibri 24pt due to eyesight and 4K monitor.

Wrapping bug occurs whenever composing a message.


Actual results:

At default zoom, the margin is somewhere at or around 40 chars. This changes to something more readable if I hit Ctrl-+ a couple of times to zoom in. If I zoom out instead, the margin decreases still further until around 22 chars!

Please see attached PDF document for examples of this behaviour.


Expected results:

The compose window font size should change when zooming in and out.

The wrapping margin should remain at 72 chars at all zoom levels, unless the font size when zoomed in is so large that the text runs off the right of the compose window.
