Hello there We have read the message We try to help If you accidentally delete your icon, you can check your trash can to see if it is still there recently. If so, you can use your mouse to restore it. If this is no longer present, you can create a new desktop icone by going to your Thunderbird folder, look for the program .exe itself and press the right mouse button where a shortcut can be created. This icon will appear again on the desktop Greetings Firefox volunteer
