I did several tests with notifications in Thundebird, and I came to the dramatic conclusion that the notifications don’t work consistently with the Thunderbird Add-In.

As workaround I am adding all Calendars over CalDAV as read-only, just to get the working notifications from Thunderbird Lightning (and to integrate the today pane). This is only because **our support partner told us we are not allowed to use CalDAV with Thunderbird.**

I activated the debug logs in the Add-In but only these rows looked relevant:

```auto

[INFO][2024-11-21T14:10:22.313Z]Console: [JavaScript Error: "The Notification permission may only be requested from inside a short running user-generated event handler." {file: "<CENSORED URL>/cal/iframe.html" line: 0}]
[INFO][2024-11-21T14:10:32.058Z]Console: [JavaScript Error: "TypeError: calTab[0] is undefined" {file: "moz-extension://<CENSORED UUID>/background.js" line: 116}]

```
