> I'm willing to bet 99% of users run their browsers fullscreen.

99% of the folks I interact with usually just use whatever size the browser opens in initially, then maybe resize it if they're reading for a while, or need to see more info. If half a pic shows up, they might try to fumble to grab a handle to resize to see more of the pic; sometimes it works, sometimes they end up giving up.

Going 'full screen' may be different than just 'as wide and tall as the monitor', because 'full screen' mode gets rid of the window chrome, which causes confusion.

The only folks I know who consistently use browsers 'full screen' are on mobile devices where that's generally the only option.

I've never had my browser in fullscreen unless it's media content.

I too prefer tabs at top than to the side, as I have four screens, 2x32' and 2x27' -- having the tabs at the top of my top screen feels more natural.

Do you mean maximized? I might agree if you do. I almost never see browsers full screen except when playing videos.

FWIW, I run my browser full screen. I run most apps full screen. By full screen, I don't mean that weird macos thing where it removes everything and locks you into a single app in a single workspace but the more standard one where the window is just expanded to fill the screen space.

The only time I run an app without fullscreen-ing it is if I don't have to do much in it or it doesn't have enough content to use up all the space anyways. Like system settings. Otherwise, I am using the app -> I am focusing on it -> I want it to take all the space it wants and show me everything going on inside it. My browser and my text editor are apps where I spend 99% of my time so they are always full screen.

I have no idea what the statistics are, but I certainly never run the browser fullscreen and I rarely see others do so.

It used to be possible to run web pages and applications not full screen. But moderne UIs are so wasteful of space, with massive icons, it has become almost impossible.

The only things I run full-screen on a big monitor are drawing programs and development tools.
