Why are some Firefox windows not cycling through the entire list of windows I have open?

Solution 1:

Move an app window from one space to another

On your Mac, do any of the following:

  • Drag the app window you want to move to the edge of the screen. After a moment, the window moves to the next space.

  • Go to the space that has the window you want to move, enter Mission Control, then drag the window up to the space you want to use.

  • Hold the window's title bar & then use the hot key for the Space you wish to move it to.

  • If you drag the window onto a full screen app in the Spaces bar, you can use the apps in Split View.
