I often use the feature where I drag my window to the left or right side of the screen to make it fill half the screen. Sometimes, when my window is like that, then I click to maximize it, it doesn't maximize, but the main menu(File/Edit/etc...) and the min/max/close buttons all disappear. It doesn't happen every time, I don't know exactly what triggers it. My browser is like that now as I type this.

What causes this, and how do I fix it(besides restarting the browser)?

Note the location of my cursor.

It's normal, as Ubuntu works with a global menu. Try to move your cursor to the top area when your application is in fullscreen mode.

You'll see the menus and windows options, as expected.


You're right. After try for a while, it happened to me too. You could try Ctrl+Alt+5 to quit this "problematic" mode.

This behavior is a bug, and a fix was commited, as you can see here.

You misunderstand. The application will not go into fullscreen mode. I know that you have to move your cursor to the top, that's the same even when it's not in fullscreen. Either way, the menu does not show up. – Benjamin Lindley Jan 3 '12 at 1:03
