Why Thunderbird Import NG Tools not working?

[jackera]

There are several reasons for Thunderbird Import NG Tools not working for several reasons. One common cause is a mismatch between the add-on version and your Thunderbird version — after major updates, some extensions can become temporarily incompatible. Additionally, running Thunderbird in Troubleshoot Mode (formerly Safe Mode) disables all add-ons by default. Corrupted profiles, insufficient folder permissions, or conflicting extensions can also prevent ImportExportTools NG from functioning properly. In some cases, outdated or partially installed add-on files lead to errors when trying to import or export emails. Keeping Thunderbird and the add-on updated, along with checking for conflicting settings, often resolves the issue.
