There have been a few reports of this occuring in the Thunderbird Support Forum. Depending upon other settings and info, three possible solutions have been discovered. 1. In some cases, Thunderbird acts like it has no mail accounts and asks you to create a new account. The 'profile' folders show the accounts and mbox files exist. There are no accounts listed in the 'Account Settings' and the 'prefs.js' file has a low size. There are other 'prefs.js' files with a number and renaming 'prefs.js' to swap to using the one with highest number got accounts and therefore folders back. 2. Others found Accounts all ok and they could send, nothing displayed in Folder Pane. A solutuion was found. - Access profile name folder - Exit Thunderbird and deleted four files: - folderCache.json - folderTree.json - session.json - xulstore.json 3. There are also cases where folder pane was completely empty, accounts were still in Account Settings and they could send. Performing fixes 1 and 2 did not work. The user in this case found that deleting just one account and then adding it back, got all the mail accounts and folders displaying again. If you need more detailed help, then please ask the question in the Thunderbird Support Forum. Have you asked a question regarding this in the Thunderbird Support forum?

Others found Accounts all ok and they could send, nothing displayed in Folder Pane. A solution was found. Please rename files so they can be used for diagnosis, not delete them. - Access profile name folder - Exit Thunderbird and rename four files: - folderCache.json - folderTree.json - session.json - xulstore.json 3. There are also cases where folder pane was completely empty, accounts were still in Account Settings and they could send. Performing fixes 1 and 2 did not work. The user in this case found that deleting just one account and then adding it back, got all the mail accounts and folders displaying again. 4. In your case you have an addon involved, so there is a potential additional fix. re : Also, all QuickFolder links broken. As you use an addon which is related to Folders. Remove the addon and restart Thunderbird. If all is ok, then the addon is the cause. Access Quickfolders addon webpage and download up to date version.
