Is there a keyboard shortcut for switching windows?
I see that there is a keyboard shortcut for switching tabs within a Firefox browser window, but I'd also like one for switching between browser windows. I imagine this is easier on Windows, where each browser window sort of behaves as a separate application, but on the Mac OS an application can own several windows. Thus, the OS doesn't provide support for switching between browser windows via a keyboard shortcut; it can just switch between applications, which brings all of the target application's windows to the front.
To switch between Firefox windows use: (Shift) Cmd + ~ (Tilde)
Command + ~ (tilde) won't work if an embedded video is on the screen. Once a different page is on top, it will work again.
