I was searching for a completely different problem but found this thread (considerably later than the last post). Sorry to necro it, but I had an inkling about the problem involving web browsers and decided to see if I was right. I currently am using the latest version of Firefox and confirmed my suspicions. There will be similar ways to resolve this problem in Chrome as well, but you may need to dig a little more to get the exact phrasing right.
From what I can tell, Samsung's Easy Setting Box utility requires a window to be dragged by the titlebar specifically in order to be applied to the program. However, all web browsers (Opera, Chrome, Firefox, Edge, etc) have their tabs occupying that space, and instead emulates titlebar behavior when you click and drag it. The reasoning behind why F11 (full screen) and leaving works (sometimes) is because it resets that behavior and changes the titlebar to be more like default instead of the way it usually works. If you want it to work consistently, at least in Firefox:
1) Enter "about:config" into the address bar to open the configuration directory.
2) In the search bar in the resulting page, type "browser.tabs.inTitlebar"
3) Change the value of the resulting address to "0"
This changes the tab's titlebar to the OS default. Tabs should no longer be aligned to the top edge of your browser. The default titlebar should be there now, and when dragging your window with it, it will, without fail, always interface correctly with the program. Again, this should be the case for all browsers that utilize a similar infrastructure. It will make your browsers less aesthetically appealing, but it will allow them to properly function with Easy Setting Box without the need for shortcuts or workarounds.
