Okay a specific post for those who use Thunderbird as an email client. Basically I had some issues with my brand new PC where it BSOD (Blue Screen Of Death) almost immediately (turned out to be a loose fan in the tower!). Upon fixing the PC I could open Thunderbird but not see any folders in the Folder Pane on the left.
So here’s the solution (I used the error console in Thunderbird to search for a possible solution):
- Navigate in Windows to the your Thunderbird profile folder (e.g. “C:\Users\YOURUSERNAME\AppData\Roaming\Thunderbird\Profiles\SOMETHINGHERE.default)
- Find the file “folderTree.json” back it up first and then delete it (or just rename it OLDfolderTree.json)
- Now load up Thunderbird, your problem should have been fixed (it seems to create a new file)!
