Thunderbird Extension: No New Window on Double Click
No New Window on Double Click 0.2.3
Released on 2005.05.26 for Thunderbird 0.7 - 1.0+ on all operating systems
This extension prevents Thunderbird from opening a new main window. When you double click on a folder in the folder pane, the folder will expand or collapse if it has subfolders. Also, when a program tries to run Thunderbird while it is already running, the new window is closed and the first main window will be brought to focus. New mail windows can still be opened when right-clicking on a folder and selecting Open in New Mail Window.
