Bug: no new mail notification popup for non-inbox imap folders, when mail is detected by polling (not IDLE)
Status: RESOLVED
Priority: --
Resolution: INVALID
Created: 2021-08-16 05:15:49+00:00
Resolved: 2021-08-27 03:38:15+00:00

Steps to reproduce:

- add an gmail label which becomes an imap folder
- in TB enable "when getting new messages, always check this folder"
- add a gmail filter to direct certain messages to this folder ("Do this: Skip Inbox, Apply label ...)
- mail.notification.count.inbox_only=false to have the tray icon indicate new mail
- IDLE seems to broken for non-inbox, so minimize the mail check interval
- have TB minimized to tray

send an email to this folder


Actual results:

when new mail is detected, the icon changes, audible alert sounds, but there's no bottom right screen corner new mail notification popup


Expected results:

new mail notification popup

Steps to reproduce:

Starting the programme.


Actual results:

The programme starts. The servers are subsequently visited for logging in, in order to check for new messages. When these are found, the standard signal is given. When any message is clicked on, the process of opening it for display is started. All of these processes are indicated in the down-left corner. But before the sequence of checking the servers is completed, the programme crashes and a crash report (see attachment) is issued.  


Expected results:

The sequence should be completed and the programme should be running until it is terminated actively by me as the only user.
By the way, none of the other programme versions is able to accept the profile that I use for many years now. I would like to convert it including all the message folders and the intensely used agenda for the use with the current version!

Actual results:

Many messages are exact duplicates.  The older, the more frequently this appears to be the case, and such that at the end of my list (> 4000 messages) they are all duplicated (so no idea of the actual number of distinct messages).  The folder seem at least 75% larger than it should be.

Bug: the update causes a conflict with McAfee

Steps to reproduce:

When I send email from Thunderbird or sometimes even just open it I get a McAfee warning that says "We stopped something dangerous. We caught something trying to hijack one of your apps. Don't worry, we took care of it."  


Actual results:

See my note above. When I called McAfee tech support they said your update most likely was causing the conflict and when you came out with a new update it would probably fix it.  They didn't believe anything truly dangerous had attacked my system, just that the update wasn't fully compatible with McAfee.


Expected results:

I would have expected to just use Thunderbird normally with no warnings from McAfee.
Bug: Encryption status incorrect for some multi user conversations when provided by protocol

Resolved: 2021-08-19 10:59:10+00:00

When the encryption status selector is shown, it never gets hidden again, leading to incorrect encryption states being reported. This is technically a regression, I think, since it would also affect OTR-only encryption.

STR:
- select a conversation with encryption available or enalbed (if you have OTR that's any direct conversation)
- select a conversation that doesn't have encryption available (either a MUC and OTR or with Matrix a MUC where you're not allowed to enable encryption)

3. Click the Send button to invoke the Spell Checker.
4a. On one or more of the spelling errors that will be found, click the Ignore button. In my case, nothing happens and the spelling error is not ignored.
4b. On one or more of the spelling errors that will be found, click the Replace button. In my case, TB just shuts down with no crash window.

There is some MAJOR bustage here. I tested 92.0b1 at home yesterday and it crashed on Spell Check so I reverted back to 91.0 stable. I just tested 92.0b2 at work and it seems there is still some bustage.

I have enabled TB Dark theme, but after restart of TB I'm seeing a mixture of dark theme and some other theme which is definitely not dark. 91.0.1 (64-bit)
I'm not sure how to reproduce this, will add more if I find something.

Tentative STR:
- switch TB 91 to dark theme
- close TB
- reopen TB
- may involve other factors/steps
- check 3pane colors
- double-check current enabled theme in Add-ons & Themes

Actual
- Folder list and message list wrongly appear in bright color, black text on whitish background (not dark), but dark theme is still enabled in the add-ons tab.
- Other tabs like Preferences, Add-ons are correctly in dark mode

Expected
- Dark theme should be used everywhere regardless of restart TB, OS sleep etc.

Two suspicious connections:
1. An IMAP connection to a server with hostname beginning with "racondbtest-ho-b0", which is not the usual server for my email services.
2. A connection to a Cloudflare server 172.67.74.82
Can you explain either of these?
I'm using only Comcast and Gandi email accounts, both are IMAP.


Expected results:

No suspicious connections.

The attached notification started to appear randomly in a loop (appearing/disappearing/appearing, etc... constantly) out of the blue! I was not even in TB version when it occurs, only noticing it when re-activating TB in the foreground...

Closing it add no effect as other ones keep appearing immediately...

Putting TB in offline mode, allowed to close the notification, which did not came back after putting TB in online mode again.

Only happened once.

91.0.1 (64-Bit) regression, works in 78.13.0 (32-bit)

STR

- Show main menu bar
- drag a TB tab to another position

Actual result (see screenshot)
- drop marker shows in menu bar

Expected
- drop marker should show in tab bar

Note that TB is not using the latest FF tab layout where tabs are irritatingly presented as buttons which are disconnected from their content.
