Enter full screen by left clicking on the page. Exit full screen by pointing on top of the screen. Since: https://superuser.com/questions/1368977/how-to-re-enable-proper-full-screen-mode-in-chrome-with-display-of-toolbar-on-ho https://groups.google.com/a/chromium.org/g/chromium-discuss/c/f9r8ZsaMm9o/m/43l1YN1KCwAJ https://support.google.com/chrome/thread/67228761/how-to-show-tabs-bar-in-chrome-full-screen-mode-just-like-in-firefox?hl=en. Why enter full screen by left clicking on the page, why don't just use the mouseenter event, no need to click? document.documentElement.requestFullscreen() needs a user gesture, to avoid abuse. But: chrome://flags/#automatic-fullscreen-content-setting https://chromestatus.com/feature/6218822004768768, the .js would be: document.addEventListener("mouseenter",$,{once:true}) function $(){document.documentElement.requestFullscreen() A=new AbortController() addEventListener("mousemove",e=>{if(e.y==0){document.exitFullscreen() A.abort() document.addEventListener("mouseenter",$,{once:true})}},{signal:A.signal})}
