The lack of vertical space on modern 16:9 screens makes them do that. You can make it 9:16 by rotating it 90°, but it isn't common so the default is no bar. Keyboard-oriented browsers often go further than that, offering just a plain page with little to no visible controls.
Anyway, at least you can easily turn the title bar back on.
I know this was the original argument 10+ years ago when this trend started, but it has long stopped any sense. Firefox' tab bar is now 48px. If you add in the insane padding of the address and search boxes, that's practically the same size -- if not thicker -- than the old titlebar + tab bar + address bar combo. No space has been saved in this manner for years now.
yeah - the huge chunk of space between 'home' and the address field is just wasted..It's plenty big enough to shrink it a bit and add some 'outside' padding to the ends of the bar.
I'd be happier if there was just more padding on the 'ends' of the address bar, and less padding 'internal' to it. The space between 'home' and address bar would be a lot more useful if it was split between the to ends and gave you someplace to grab.
yeah. I'm blind as a bat, so I only get 1 window per monitor anyway - so the extra space wouldn't be an issue.
P.S.
Am I the only one losing the fight with smaller pixels? As monitors get higher res, I keep having to increase the font size to be able to read them. Even on 4K, twenty-mumble inch monitors, I can only get one 'visible' window at a time.
