1977535 - Make “Show missed reminders for writable calendars” enabled by default, or provide user feedback when reminders are suppressed

Status: RESOLVED DUPLICATE of bug 1988288

(Calendar :: Alarms, enhancement)

Description

[pierre12345]

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:140.0) Gecko/20100101 Firefox/140.0

Steps to reproduce:

Upgrading from TB 128.x to 140.0

Actual results:

Past reminders that had not been yet dismissed no longer reappear when TB is closed and reopened. They use to come back in all prior versions of TB.

In Thunderbird 140.0, calendar reminders that were active when Thunderbird is closed do not reappear on restart unless the option Preferences > Calendar > Reminders > "Show missed reminders for writable calendars" is checked.

But the option is unchecked by default (at least after an update from 128 to 140.

This behavior surprises long-time users, since earlier versions of TB always re-showed active reminders on relaunch.
Feels like data loss, since there's no indication those alarms existed or were dismissed.
Can cause missed events, as there's no prompt or hint that the setting needs to be enabled.

Expected results:

Enable the setting by default, especially for upgraded profiles.

OR warn the user when they quit Thunderbird with open alarms, if the setting is disabled.

OR highlight the setting after upgrade or when first syncing a calendar.
