I want to use firefox as a front-end for users to see only one website.
I found how to start firefox in fullscreen, toolbars are hiding by default, but I cannot make the toolbars (address bar, tabbars etc) not showing up when the user hovers on the top of the screen.
Is there a way to do this?
Got to about:config , search for browser.fullscreen.autohide and change the value to true.
Possible values and their effects
True
Automatically collapse toolbars and the tab strip in fullscreen mode and only show on mouseover. (Default)
False
Always show the toolbars and tab strip in fullscreen mode.
You can advantage of HTML5 Full Screen API.
Paste code below into console and click big black box to activate fullscreen mode:
(function() {
var el = document.createElement('div'),
docEl = document.documentElement;
el.innerText = 'Go to fullscreen view';
el.setAttribute('style', 'position: fixed; top: 10%; left: 10%; padding: 30%; background: #000; color: #fff; opacity: .7; cursor: pointer;')
document.body.appendChild(el)
el.onclick = function() {
if (docEl.requestFullscreen) {
docEl.requestFullscreen();
} else if (docEl.mozRequestFullScreen) {
docEl.mozRequestFullScreen();
} else if (docEl.webkitRequestFullscreen) {
docEl.webkitRequestFullscreen();
}
document.body.removeChild(el);
};
})();
...or use bookmarklet:
javascript:(function(){var e=document.createElement("div"),t=document.documentElement;e.innerText="Go to fullscreen view";e.setAttribute("style","position: fixed; top: 10%; left: 10%; padding: 30%; background: #000; color: #fff; opacity: .7; cursor: pointer;");document.body.appendChild(e);e.onclick=function(){if(t.requestFullscreen){t.requestFullscreen()}else if(t.mozRequestFullScreen){t.mozRequestFullScreen()}else if(t.webkitRequestFullscreen){t.webkitRequestFullscreen()}document.body.removeChild(e)}})();
As lexu mentioned, what you want is typically called "kiosk mode". To my knowledge, Firefox does not include built-in kiosk mode functionality (I think only IE includes it in the base version), but it is available with a couple of different Firefox plugins.
R-Kiosk is perhaps the most popular one. I've used it before in one of my previous jobs with a Firefox 3.x setup, but I haven't tried it in a couple of years so I don't know about compatibility and functionality with newer browsers. It does state it works through the latest versions of Firefox.
The other fairly popular one is FF Fullscreen which I haven't tried, but doesn't appear to be a full kiosk mode that prevents users from getting to the desktop, but rather just a fullscreen with no toolbars mode, which might be what you're looking for anyway. Your question didn't state whether or not you wanted to keep users from getting to the desktop.
On new Firefox v.71 currently on Nightly (Beta) you can add --kiosk when running to avoid all bars (navigation and tabs)

An alternative is the 'Old Lion Fullscreen' addon. If works reliably (unlike FF Fullscreen which seems to have unpredictable full-screen behavior). The only drawback is that the menubar does not appear when hovering near the top.

Drag everything from the bars to the window opened by Right Click > Customize.
Go to Options > Tabs and disable Always Show Tab Bar.
Right Click and disable all four bars.
Hit F11 for full-screen mode, it should be kiosk-like if you only have one tab open.
This, however does not disallow the user from using shortcut keys to open new pages / tabs / windows.
Even when using an add-on or extension, it does not disallow the user to mess with the system. This is simply because Firefox doesn't seem to provide the mechanics to allow for a fully implemented kiosk mode, and since they haven't implemented it themselves someone has to take the source and write a kiosk mode himself.
You might want to try an alternative browser like Opera's Kiosk Mode, also look into the Group Policy of Windows to block additional shortcut keys like CTRL+ALT+DEL and other user functionality...
How about
javascript:(document.onclick=()=>document.documentElement.requestFullscreen())();
This code is nice, because
1) It uses the modern requestFullscreen API.
2) Some browsers, Firefox for example, prevent full screen request without a user action. This code will enter fullscreen when the user clicks on any part of the page.
Way 1:
Firefox's built-in "hide toolbar" option can be used as seen below image.
Way 2:
Modern Kiosk doesn't work like a char yet does fill the bill. On your current tab, set current url as kiosk then enter kiosk mode.
