Dear Maintainer,

the very latest version of Thunderbird crashes at startup but it doesn't if started in "safe-mode"; however resetting the UI and disabling the addons permanently did not solve the issue, a fresh start did not solve the issue.

# PROCEDURE TO REPLICATE THE ISSUE
Open a terminal; digit thunderbird; enter.
