Conflict between Firefox and Thunderbird

Each time I open Thunderbird, Firefox randomly switches to another window. When I set Firefox back to the proper window, Thunderbird closes.

Using Windows 11, Firefox 130.0.1 and Thunderbird 128.2.3esr.

I suspect the problem is with the latest release of Thunderbird. I want to install the older Thunderbird 115.10.1, but I did not find an easy way to do that.
