Thunderbird ஆதரவு மன்றம்

Thunderbird shows Hijri (Saudi Arabia Regional Date Format) no matter what Preference I choose in settings.

I've chosen the English (United States) Application Locale and restarted Thunderbird multiple times but in the header the date still shows in Hijri Format (1445-xx-xx). See attached images.

Am I missing something here? Couldn't find any clues in the config editor either. The version I have installed is the correct one (English US).

Related: https://forums.mozillazine.org/viewtopic.php?t=3079875 I used to daily version 52, and this would allow you to in windows set it to show the new mail tray icon, but hide the normal tray icon.

Seems since the introduction of mail.biff, this was unified and it's no longer seperate entries in the windows Taskbar Settings -> Select which Icons appear on the taskbar menu. Attached image shows the 2 old entries, and the singular new one which is the same, unread notification or not in the tray icon. I can only select/deselect one thunderbird entry here, which just toggles if it's there at all or not.

I do not wish to see the normal tray icon. I wish for the tray icon to show in my tray bar when there's a new/unread message.

This seems to be a thing that was regressed and fixed in v68, and then became an issue again with biff's introduction in v91 forward?

Thanks for your time.

My code is as follows: thund = "C:\Program Files (x86)\Mozilla Thunderbird\thunderbird.exe " & _

       "-compose " & """" & _
       "to='" & email & "'," & _
       "attachment='" & Attachment$ & "'," & _
       "subject='" & subj & "'," & _
       "body='" & fullBody$ & "'" & """"
   Call Shell(thund, vbNormalFocus)
   Sleep 3000
   AppActivate "thunderbird"
   SendKeys "^~", True
   Sleep 3000

   SendKeys "^{ENTER}", True
   Sleep 3000

   SendKeys "%fd", True

I changed the columns to be shown in the tasks view and have it sorted by due date. But every time Thunderbird starts, it resets my view settings for the tasks and shows me the default columns and order. How can I fix it?
