On macOS (Sonoma for me), if a Firefox window has focus and and there is a window that doesn't have a dock icon (for example, the "About This Mac" window) that is behind the Firefox window, using Mission Control to bring that window to the front doesn't work. Well, actually it does work, but then the Firefox window immediately comes back to the front. If any other app has the focus, then it works correctly (Firefox doesn't force its way back to the front). Does anyone else experience this, or is it just my system?
