My Thunderbird installation now crashes upon start. Yesterday I updated my Thunderbird to the new version, via the "About Thunderbird" menu item. It gave me the Crash ID: bp-720aa7bf-f084-4991-9b1c-8d03e0220702 I tried starting Thunderbird in safe mode, first checking the "Disable all add-ons" (still crashes), second checking "Disable all add-ons" and "Reset toolbars and controls" (still crashes). The Home/Thunderbird/Thunderbird Crashes directed me to come to the Support forum and ask for help there. Any suggestions will be welcome. Thank you.
