A few months ago I noticed the bar across the top Firefox screen that has the buttons to close, minimize, and full-screen disappeared. Now suddenly I'm getting this:
Since I no longer have the 'full screen' button, and can't drag the window bigger, I'm only getting 1/2 of a window. Weird.
I can hit F11 and it'll full screen it but then I lose the menu up top. I'm assuming I can open a terminal window and type in something to fix this, but I'm not smart enough to know what to type.
