Restore Thunderbird’s missing folder pane

Friday, January 27th, 2012

Here’s what to do if your Folder Pane disappears. The Folder Pane is the left one that shows the tree of mail folders: Inbox, Sent, Drafts, etc. If there is no space there (the other panes extend to the left side of the window) it is probably just not displayed, and you can drag its resize bar from the left, or display it with the View menu.

But if the Folder Pane just comes up as a blank space, it could be due to a previous crash of Thunderbird, or corruption of some auxiliary files that need to be rebuilt. Here’s how to fix it:

  • Exit Thunderbird
  • Find your profile folder.  In Windows, you can navigate directly to your profile folder at the following path:
       C:\Users\<user>\AppData\Roaming\Thunderbird\Profiles\<profile>\
  • In Linux, look for it here:
       ~/.thunderbird/<profile>/
  • or here:
       ~/.mozilla_thunderbird/<profile>/
  • The AppData folder might be hidden: to show hidden folders, open a Windows Explorer window and choose
    “Organize → Folder and Search Options → Folder Options → View (tab) → Show hidden files and folders”
  • You can (should) make a backup copy of your profile folder now, in case something goes wrong
  • In the profile folder, rename the session.json and foldertree.json
    files (to session.json.bad and foldertree.json.bad)
  • Restart Thunderbird

If something goes wrong, you can restore your old session.json and foldertree.json files, then go searching for a different solution.
