Bug: Message  detail pane not rescaling when subject too long
Status: RESOLVED
Priority: --
Resolution: WORKSFORME
Created: 2022-01-16 11:02:41+00:00
Resolved: 2022-10-02 23:52:26+00:00

Steps to reproduce:

For RSS messages the pane showing Author, Subject and Website doesn't change height when switching/deleting between messages.


Actual results:

The pane not rescaling means that for messages longer than a line the top fields push down the lower ones, resulting in the Website line not being displayed. This seems to occur only if the lines get longer not shorter.

See attached screenshot. Top showing what the pane should look like, bottom is the faulty one. Note the the tiny red specks on the bottom, that is the only bit of the Website line visible.


Expected results:

The pane should rescale to the correct height when switching between items.

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:90.0) Gecko/20100101 Firefox/90.0

Steps to reproduce:

When I select a multiple emails (more than 2 or 3) I can no longer see the the message "These messages take up X kb/mb". Neither zooming out or removing toolbars/changing display seems to help. 


Actual results:

"These messages take up X kb/mb". is hidden 


Expected results:

"These messages take up X kb/mb".  should always be visible. (it used to be in older versions)
Bug: Contact's Primary eMail isn't suggested first in outgoing message
Status: UNCONFIRMED
Priority: --

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/97.0.4692.71 Safari/537.36

Steps to reproduce:

(Example) Contact record "John Smith" has three eMail address listed in this order:
ccc@gmail.com
bbb@yahoo.com
aaa@mac.com

The "ccc@gmail.com" is listed first and is starred.
No other contacts are named "John".
No other eMail addresses in the Addressbook begin with "ccc".




Actual results:

When creating a new eMail and typing in the outgoing eMail address, typing either "john" or "ccc" displays all three addresses but in the following order:
aaa@mac.com
bbb@yahoo.com
ccc@gmail.com
...with the first address highlighted.



Expected results:

The primary eMail address (the first one listed in the Contact's record) should have been the default (highlighted) eMail address so a simple "Enter" would choose it and place it into the "TO:" field.

Note the attachment showing TBird's claim that the first eMail address in the Contact record is the primary address.
Bug: Unwanted mailto: handlers added to Thunderbird by default

Resolved: 2022-02-02 12:35:53+00:00

Bug 1733497 moved some regional settings for Firefox into uriloader/exthandler/HandlerList.jsm. These include mailto: handlers which are inappropriate in Thunderbird (clearly) and also cause any test which opens the Preferences tab to fail by attempting to load the GMail favicon.

I'm going to make a temporary fix for this so that we can get our tests back again. It may turn out to be a long-term fix if we determine that we aren't ever going to use data from HandlerList.jsm.

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:95.0) Gecko/20100101 Firefox/95.0

Steps to reproduce:

Installed Thunderbird on the D: drive of my computer.


Actual results:

Thunderbird will not update automatically or when I manually trigger an automatic update. I had to actually download the program then install it over the outdated version which worked fine. The installer was able to detect that the program was installed on "D:\Mozilla Thunderbird".


Expected results:

This has never worked for me, but I believe that the program should have updated automatically without my intervention. I'm guessing that is what is supposed to happen.

Bug: 'Add Security Exception' dialog omits port number when trying to add CalDAV network calendar from server running on port 5006

User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:95.0) Gecko/20100101 Firefox/95.0

Steps to reproduce:

I'm using Thunderbird 78.14.0 on Ubuntu 20.04.3 LTS and want to add a CalDAV network calendar in a fresh profile.
The URL looks like this: https://server:5006/Tausch/Kalender/Kalender
The server is a Synology DSM (6.2.4-25556 Update 2) and it's using a self-signed certificate.


Actual results:

I get the 'Add Security Exception' dialog, but the Location omits the port number 5006, it just have: server
So when clicking 'Confirm Security Exception', the port number 443 is added to server.
Therefore there is no connection possible and the dialog pop ups again.


Expected results:

The 'Add Security Exception' dialog should not omit the port number.

As a result of bug 1741745 and [what I did to fix the decision task](https://hg.mozilla.org/comm-central/rev/16cdc671aa78245841c56a6c3cf6b78ff8cc866c), GTest hasn't run on TaskCluster since December 14. I think what is missing is the 1proc variant that's defined on mozilla-central. We don't have any variants at the moment so that mechanism would need to exist too.
Bug: displaying attachments: Decoding of filenames with backslashes removes too many backslashes
Status: UNCONFIRMED
Priority: --
Created: 2022-01-18 08:57:55+00:00
Resolved: 2022-01-19 11:42:28+00:00

Steps to reproduce:

On Linux systems, the following are valid filenames. (I would not use them, but they are valid)
- a"b.txt
- a\"b.txt
- a\\"b.txt

Attaching them to an email (e.g. creating a draft email and then looking at the mail's source), Thunderbird correctly encodes those names as
- filename="a\"b.txt"
- filename="a\\\"b.txt"
- filename="a\\\\\"b.txt"


Actual results:

Displaying the email in the UI displays the attachments as
- a"b.txt
- a"b.txt
- a\"b.txt
This obviously uses one "backslash de-escape" too many.


Expected results:

When displaying an email, the filename should be the same as it was when attached.
- a"b.txt
- a\"b.txt
- a\\"b.txt

I chose the context menu from the Desktop (Windows 10) and "send to" "mail recipient" in the message created in this way when saving the attachment, the size of this attachment is 0. The same when I create a message from an external program with a pdf attachment. 
In Thunderbird 78 its OK.


Actual results:

since upgrade to TB 98, I called my ics file in my own server like this : ftp://myid:mypassword@mydomain.com/xxx.ics
changing, adding, or deleting anything on mu calendar in thunderbird changed it automaticaly in my server.


Actual results:

now, thunderbird dosen't find my ics with this method : ftp://myid:mypassword@mydomain.com/xxx.ics but can find it with this one  https://myid:mypassword@www.mydomain.com/xxx.ics but naturally I can't make any change in the file with this method.
With ftp method, automaticaly at each refresh, system ask me which application I want to use to open ftp, and import nothing if I choose thunderbird.
With http method I just can read only my calendar.


Expected results:

Until thunderbird 78, this worked for all the 3 calendars of my society. 
Thunderbird read the calendar with ftp method, and changed it on my server.

Steps to reproduce:

Email account seems to work fine, but when opening a PDF attachment, the old autoconfig-filled account info appears in the address bar:  "imap://mbw%40removethis%2Euw%2Eedu@.removethis.uw.edu:993/fetch%3EUID%3E/INBOX%3E136928?part=1.2&filename=Support%20Service%20Number%206231628.pdf&type=application/pdf"

Autoconfig generates a "mbw@removethis.uw.edu" address that I must manually change to "mbw@uw.edu" - after this is done I never see the "removethis" anywhere except when viewing an attachment. 


Actual results:

I havent extensively tested it, but this appears to makes the attachment un-viewable


Expected results:

at the time I modify the account info, changing the "mbw@removethis.uw.edu" to "mbw@uw.edu" I should never ever see the "@removethis.uw.edu" domain used anywhere. Thunderbird appears to be keeping it in the "AlternateServices.txt" file and using it for attachments

Actual results:

There's a problem achieving focus in the Message Pane when selecting a message and then moving the mouse from the Message List pane to the Message Pane and stopping. Cannot scroll the window with the mouse until moving the mouse around for a second or two first.

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:91.0) Gecko/20100101 Thunderbird/91.5.0

Bug: Cannot import from Thunderbird release into beta (when server directory outside of the profile)
Status: RESOLVED
Priority: --

(Not sure if this should go here or in MailNews Core:Import; apologies if it's in the wrong one.)

When attempting to import my profile from Thunderbird release into beta, I receive the error "Component returned failure code: 0x80520001 (NS_ERROR_FILE_UNRECOGNIZED_PATH) [nslFile.append]".  (This text is not copiable, which is a huge pain.)  It appears that at least part of my profile did import successfully; I see all (or at least most?) of the folders, but I can't see the mail in them, and the layout, etc. are different.

Interestingly, about the fourth time I started Thunderbird, it asked me for passwords for my email accounts.

STR:
1. Start Thunderbird
2. In the main screen (which may be for an account), click "Import".
3. Import Everything
4. Thunderbird (profile folder)
5. Find the folder (default-release)

Please let me know if there is anything I can do to help.
