After update date/time format wrong and cannot change
After accidental change to Thunderbird 140.0.1esr (64-bit) all date/time display changed to American format (7/16/2025, 12:55 PM) where it used to be the settings of my machine (Win10 64 bit, language English, region Netherlands): short date dd-MM-yyyy long date ddddd dd-MM-yyyy short time HH:mm long time HH:mm:ss I tried overriding the setting using the config editor and inserted ntl.date_time.pattern_override.date_short and ntl.date_time.pattern_override.time_short, restarted TB which promptly lost the new settings (not saved). Also the Message List Display Options defaults to Cards view after restart, even after changing to Table view.
Please help!

Since TB refused to accept any config changes I started searching for the file(s) where such changes might be saved, and found the prefs.js. This file turned out to be read-only and not containing the settings I wanted. While TB was down I made the file editable and inserted user_pref("intl.regional_prefs.use_os_locales", true);. After starting TB all problems seemed to be solved, and strangely enough, the file was made read-only again. For now the problem is solved, but what is the use of a config-editor if it ignores changes without any warning that changes cannot be saved?
