This ThunderBird add-on stops the program from opening a new main window when double-clicking, eliminating the hassle of unnecessary windows.
One of the benefits of this extension is that it allows you to expand or collapse a folder with subfolders by simply double-clicking on the folder's name in the folder pane. It is a welcome addition to those who use Thunderbird for email and want to be able to navigate their email folders more efficiently.
Another advantage of No New Window on Double Click is that it prevents multiple windows from popping up when a program tries to run Thunderbird while it is already running. Instead, the new window is closed and the original main window is brought to focus.
While some may argue that this extension limits your ability to open new windows, it is still possible to do so by right-clicking on a folder and selecting "Open in New Mail Window".
Overall, No New Window on Double Click is a handy tool for those who want to streamline their email management and is compatible with Thunderbird versions 0.7 or later.
