Package: thunderbird Version: 1:102.9.0-1~deb11u1 Severity: important Thunderbird uses an incorrect SQLite endianness when built on a little endian ppc64 (ppc64el) system. As a result, it is unable to initialize and load its databases, leading to a blank / unusable application.
There is some discussion upstream and potential patches at https://bugzilla.mozilla.org/show_bug.cgi?id=1757271
