Questions[titlebar](ubuntu)

Since upgrading to Ubuntu 18.04 from Ubuntu 16.04, the titlebar buttons on the upper left corner of the window for closing, minimizing and maximizing windows have vanished.

Then I went to GNOME Tweaks (GUI menu) --> Windows --> Titlebar
and set the options to add maximize and minimize buttons to the title-bar. However there was no option for Window close button there:

Things I have tried to correct this

1. I installed gconf-editor and tried this gconf-editor solution
2. I did not understand the solution (if any) provided here

Output of the command

gsettings get org.gnome.desktop.wm.preferences button-layout

Output: 'minimize,maximize'

I've tried the following shell extensions:

• pixel-saver
• Unite
• No Title bar
• Gnome Global Application Menu (HUD Gnome)

but none of them work on Ubuntu 19.04 and the title bar is really annoying. Are there any solutions that i could remove it or merge it with top bar?

I've looked through

• Wasted screen space due to multiple horizontal bars at the top when an application is open in GNOME desktop
• Ubuntu 17.10 windows' menu in panel
• Hide maximized title bar in Ubuntu 18.04
• On Ubuntu 18.04 can I hide the title bar AND still see the close/minimize/maximize icons?

and more with no luck.

This is for all programs not just Firefox. I would like 18.04 to behave a bit more like Unity.

I am using Ubuntu 18.04. I realize with GNOME, or its extensions, I can do things like hide the title bar. However, I want to hide the title bar and still see the windows management icons like on Mac OS and Windows.

Is this possible?

Any way to fix this in Chrome?
