Rated 5 out of 5 stars
Have Thunderbird 52.x.x installed on two Macs running El Capitan. Both computers show entered lightning calendar events as starting at 00:00 in day and week calendar views. Does not matter what the start time entered is, the event shows up in these two view modes as starting 00:00. Makes the calendar virtually useless. In lightbird it is fine - it displays it as it should. I personally would prefer to have the calendar tabbed as in Lightning, but until that is fixed this add-on solves the problem we are having. Hoping it will continue to run problem free.
Thank you for your efforts - will gladly donate.
Actually it shouldn't be different, but glad it works for you. :)
