User Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:67.0) Gecko/20100101 Firefox/67.0

Steps to reproduce:

I have many CalDAV calendars (Google, Davical, DavMail) with a lot of events. Leave open the "Find Events" list with the item "All Events" selected and restart Thunderbird.


Actual results:

Thunderbird is unresponsive for many minutes, cpu at 100%.
If at startup the "Find Events" list is closed, or the selection is not "All Events", or the calendars are simply unchecked the problem does not occur. Opening "Find Events" after startup does not cause the problem (the list of events is created quickly).
This problem also exists in earlier versions.
Possibly related to bug 1266146


Expected results:

Thunderbird should work after a few seconds.
