Hi,

I have a quite new Thunderbird installation on a new Win 10 PC. Usually I open some e-mails in tabs and keep them open to remind myself of the most impotant e-mails.

Thunderbird saves those tabs and opens them again when I restart. This function suddenly stopped working. Now it always keeps the exact same 3 emails. If I close them they will still be opened, and new tabs won't be saved. It seems to always restored that exact session.

How can I fix this?

thanks in advance

Try this: In Thunderbird Help > Troubleshooting Information Under 'Application Basics' section about 8th in list is 'Profile Folder' - click on 'Open Folder' button A new window opens showing the content of your 'profile name' folder.

Exit Thunderbird now.

Look for and delete the following files:

  • session.json
  • xulstore.json

Restart Thunderbird.

Please check your computer to see if there is any program like CCleaner (some Anti-Virus products also can do this) which is cleaning up eg:session, cache etc files. Thunderbird profile folder needs to be made exempt from any 'cleaning' activity.
