You can try using the "Window Class" match condition, or the "Window Text" match condition in your trigger instead, which may only catch the main firefox windows.

Hope that helps! ]]> https://www.displayfusion.com/Discussions/View/child-windows-open-in-fullscreen/?ID=57cf647c-8c21-41e4-9ae4-c641b5b06b97#3 Tue, 11 Jan 2022 13:32:25 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/child-windows-open-in-fullscreen/?ID=57cf647c-8c21-41e4-9ae4-c641b5b06b97#3 DisplayFusion I exactly followed the instructions given in the DisplayFusion help ie. DisplayFusion → Help (https://www.displayfusion.com/Help/?Version=9.9.0.0) → Window Management → Launching and Positioning an Application on Startup (https://www.displayfusion.com/Discussions/View/launching-and-positioning-an-application-on-startup/?ID=a0f16c60-9c49-486f-a300-fe37589fb9d8#first) for Firefox. This uses a trigger rule and a trigger event. I have attached the Edit Function Window for the Function. ]]> https://www.displayfusion.com/Discussions/View/child-windows-open-in-fullscreen/?ID=57cf647c-8c21-41e4-9ae4-c641b5b06b97#2 Mon, 10 Jan 2022 19:05:29 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/child-windows-open-in-fullscreen/?ID=57cf647c-8c21-41e4-9ae4-c641b5b06b97#2 DisplayFusion Are you using a trigger to open this window? If so, can you send me over a screenshot of the trigger you have setup?

Thanks! ]]> https://www.displayfusion.com/Discussions/View/child-windows-open-in-fullscreen/?ID=57cf647c-8c21-41e4-9ae4-c641b5b06b97 Sun, 09 Jan 2022 10:19:38 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/child-windows-open-in-fullscreen/?ID=57cf647c-8c21-41e4-9ae4-c641b5b06b97 DisplayFusion Hello, I've used DisplayFusion to open a program in full screen on a specific monitor. Unfortunately, almost all other child windows of the program, eg. open, find, replace, also open full screen on the specified monitor. Some modal windows, eg. print, retain their previous behaviour. How can I make child windows behave as before? ]]>
