Is there a way to accomplish this? Sadly the keyphrase searches result in issues that are similar but not the same.
Lately I've found that firefox randomly moves from one monitor to the next monitor when I open/close tabs via the middle mouse button. I like the function for other programs but don't use it in firefox at all, so disabling it just for that would be ideal.
In the DisplayFusion Settings > Compatibility tab, you can add in the app and turn on "Disable middle-click window moving (this application only)" and it should fix that up
