Some tabs always reopen after restarting Thunderbird

I had 3 tabs always opened for several months. (Thunderbird updated twice during this period, this might be important)

Now, I have no more need of those tabs. I close them, but whenever I restart again Thunderbird, they always reopen. (Didn't try deleting them or moving them to another folder yet)

Same behavior happens if I restart Thunderbird in safe mode, close the tabs and reopen Thunderbird.

( I uploaded a video showing the behavior: https://youtu.be/OPsmRp_-hBs )

Select Help/Troubleshooting Information, click Open Folder to open the profile folder, close TB, delete session.json, restart TB, and see if the open tabs arrangement at TB exit is retained when you restart TB.
