was a misguided choice by a Firefox developer. He made the time
and date display follow your Thunderbird UI language instead of
your system regional settings like before.
In your settings, you have a choice whether to use the UI language
or the OS locale for time display. Please check there. The exact
result will also depend on your OS.
FWIW, even with that set to OS locale, Firefox and Thunderbird
will still not honor the exact OS regional settings anymore, but
merely the locale. For example, if you set your OS regional
settings to use "2019-03-12" format, then older TB would use that
format, while newer Firefox and Thunderbird will ignore the exact
configuration and just use the standard format for the OS language
(e.g. "12.03.2019" for German) or TB language (e.g. "03/12/2019"
for en-US). <br>
So do we have a bug to fix this in a user acceptable manner. Like
fix the regression the change caused? Using locale only is simply
not acceptable to a lot of users, me included really.<br>
