Hi I'd like to know how to enable/ disable the tab bar on Firefox for Android. When enabled the wanted tab bar is located at the very top of the application's view above the url bar. The tabs in it appear side by side and can be scrolled horizontally. See attached picture for clarification. On my own phone (pixel 1) I have the bar enabled. On my girlfriend's phone (pixel 3) it's obviously not enabled. I searched and compared the settings but wasn't able to activate the tab bar on the other phone.
