After fullscreening a youtube video and then going back to the normal browser window, when I maximize the Firefox window, it maximizes it over my whole monitor instead of within the current Displayfusion section.
Only way that I found to fix this is restarting Firefox.
I tried the same thing with Chrome and it seems to work there as intended (and as it did with Firefox previous to Displayfusion 12.0)

So in summary and steps to reproduce:
1. open firefox
2. go on youtube and start playing a video
3. maximize the youtube video (youtube maximize button or pressing F11)
4. bring back the youtube video to normal browser window (youtube maximize button or pressing F11 again)
5. maximize browser window (windows maximize button)
6. the browser window is no stretched over the whole screen ]]>
