Maximize Message Pane for ThunderBird is a convenient add-on that collapses the thread pane and maximizes the message pane to improve viewing and reading experience on ThunderBird.
In case the problem persists, before giving up and recreating your profile, do not hesitate to ask for help via email or by posting on the blog.
The primary feature of Maximize Message Pane is collapsing the thread pane, allowing you to read messages in a larger area. Other key features include hiding the folder pane, changing folder selection from the toolbar button, hiding the message pane by toolbar button, saving visibility of the folder pane and last selected message, and changing message selection by the navigation bar when the message pane is maximized.
