New behavior when opening Firefox on Linux Mint

Hey FF Support Team, I am using Firefox version 157.0.1 (64-bit) (mint-001-1.0) on Linux Mint 22.3 Cinnamon. 4 Monitors are connected. In a previous version, don't know which but it is not long time ago, Firefox opened, when I clicked on the task bar icon, always on the monitor, where I moved the mouse to. Now in the writen version above, it is opening on the monitor, where the last Firefox window was closed. It used to be so easy to tell Firefox where to open a new window, but that feature is gone now. Or is there maybe a setting somewhere to turn it back on? I didn't find anything in about:config, though. Please do not confuse the behavior described here with the System Settings feature > Moving and Resizing Windows > Location of newly opened Windows, which works differently and is, unfortunately, very impractical. I hope you can give me the key tip Best regards Mario
