My Thunderbird Icon on the taskbar has changed and I can't get back to the original icon
My Thunderbird Icon on the taskbar has changed and I can't get back to the original icon. Attached is a picture of the task bar where the white rectangle with the "2" in red, is now the Thunderbird shortcut. I've tried a right click on it, then right click on thunderbird, then properties, then change icon, but it doesn't change it. I've looked online for other advice and am about to tear my hair out. I would appreciate any clue, and thank anyone in advance for advice.

My suggestion is to install the same version of Thunderbird over the top of the installation, the assumption being that the reinstall would update registry settings.
