I have switched to kubuntu 22.04 from windows and I am liking it. But the fact that Three Control options ( minimize, maximize, close) are taking its own row is very annoying.
I do not need title at window's titlebar.
like This Firefox.
But Brave browser is quite good with its own setup.
How can I make firefox and all other windows like those things in a single row?
In Firefox, click the hamburger menu (≡), then "More tools" - "Customize toolbar". In the bottom left corner, remove the checkbox before "Title bar".
