Era perfetta fino a qualche giorno fa, adesso scompaiono gli eventi. Forse entra in conflitto con Google Calendar? Non lo so, ma così diventa pericolosa.

You are probably talking about Lightning itself, not Calendar tabs, it has nothing to do with events. It just adds tabs over the calendar.

Es hat keine wirkliche usability und integriert sich nicht gut in den Kalender.

It should be in the main menu. See new screenshot which I uploaded to addon page.

Dall'ultimo aggiornamento di Lightning qualcosa non funziona più bene: se si effettua una modifica da Google Calendar, la sicronizzazione da Lightning entra in conflitto e non si riesce ad annullare la sovrascrittura dell'evento, perdendo così le modifiche fatte da Google.
Inoltre, ancora peggio, nel momento in cui si pospone o si chiude un evento dal pannello di notifica, l'evento sparisce dalla visualizzazione del calendario.
Spero che questi bugs vengano risolti al più presto.
Al momento ho dovuto sospendere l'uso di Lightning a favore di Google Calendar.

It works for me under 78.7.1. If you just updated Thunderbird and it stopped working try to uninstall the addon it and install again.

Works fine with TB 68.5
It took a little time to determine the meaning of "new period tab".
It would be nice if the developer could actually color the tabs themselves.

I love this add-on. But could you guys fix it please?

When I select `Today` the calendar itself is correct but the month tab is last month.

The bug started around Thunderbird 52.4.0 & Lightning 5.4.4. I am now up to 5.7.0 & 5.4.7.

Update: I found the github for this add-on and posted the bug there. Hopefully he'll fix it.

Seems to always show the previous month as selected. Very confusing.

Thanks for developing this. However, there is a bug (that I believe others are reporting)--the highlighted tab shows the wrong dates. For example, in week view, Lightning will display week 2 in X month, while the tab from this add-on highlights and displays week 1 in X month.
