Thunderbird 152 automatically creates a folder named “thunderbird”

[Kaiyu_Linux]

When starting Thunderbird Linux version 152, it automatically creates a folder named “thunderbird” (without a dot) in the home directory. The bug appeared in version 152, not in version ESR 140.

Even after clearing the data, it's still like this.

OS: Arch Linux 2026, Desktop: GNOME

Been happening for a while now, also happens on Debian/Sway.
