@macone999 To install the add on, go to Tools - Add Ons and go to Extensions. Click on the cog drop down menu and choose 'Install Add-on From File'. You can then find the file on your system and install it.

To use it (once Thunderbird has restarted) go to Tools and there is a new menu item called 'Manually Sort Folders'. You can then reorder the accounts (from the Sort Accounts tab).

The Add-On works perfectly, thanks loads Jonathan.

This review is for a previous version of the add-on (1.1.1).
