I use the last firefox release (45.02) on windows 7.
I want to prevent user to resize manually the windows. I have a non responsive GUI, and I want to fix the browser interface.
I can't use the javascript resizeTo(...) function because of MDN docs
You can't reasonably do this. Which is a Good Thing. The user is in control of their browser, not you.
You can control the size of a popup (including whether it can be resized), within reason, so temporarily while you sort out the responsive thing, you could provide users a link to open a window in the size you want:
Open window in XxY for best experience of this site.
then
document.getElementById("open-window").addEventListener("click", function() {
window.open("http://example.com", "", "width=640,height=480,resizable=no");
}, false);
Note that some browsers may still allow resizing, either in the normal way or via a small "grippy" (as the Firefox folks call it).

I would like to create a client-side screen capture of the actual webpage without a browser extension. Some bug reporting sites solved this problem so it seems to be possible. Browser compatibility is not an issue. It is ok if it works only on modern browsers.
I have tried html2canvas, but want a more accurate representation. So try to use WebRTC getDisplayMedia. I have tried the WebRTC example.
It works, but the screen selector dialog has too much information. Screens, apps, tabs. Besides this, it doesn't reflect the actual site design.
In my case, I want always the actual browser screen where the user clicked the capture button.
Is there a way to preselect the current tab and eliminate the screen selector dialog?
Or maybe some other solution/technology?
I have a JavaScript to re-size all my popup windows:
function resize()
{
window.resizeTo(240,230);
}
But now it is not resizing in Mozilla Firefox, but it was doing earlier, also
or if the popup window is opened in a new tab, it is not resizing, also in some browsers it is not also. Is there any piece of JavaScript code which works in all scenarios and all browsers?
Firefox comes with a preference for user to allow/disallow resizing of
window using Javascript. It's in Tools - Options - Content - Enable
Javascript -> [Advanced].
I am not sure if resizing is disabled by default, but you might want
to check your own Firefox installation first.
If it's disabled by default, then unfortunately there is nothing you
could do to resize the window after it has been opened. An ugly
workaround would be to open itself once again using window.open() with
the preferred size though.

I'll also add that:
You can't be assured that any browser will let you control the size of
windows you create. You can't even be sure you'll get a window at all
- people can instruct their browsers to open all new windows as browser tabs

I am developing a web-based database that needs to be opened through firefox web browser(because of some css3 elements). I want the page to open automatically in full screen mode. I dont want the user of the database to have access to the firefox menu items
Can't be done if you just have control of the webpage. Controls in the webpage cannot cause changes in the browser instance itself.
It would be a security issue if that were allowed. You could look into writing a Firefox extension to do that, as they have more access to the browser instance itself.
You shouldn't look at trying to hide the firefox menu controls. That seems like a flaw in your problem-solving approach.
You will want to look at Fullscreen APIs of the browser. If you accept a small request/info to the user in the application it can be done quite easily. You just can't force the user into Fullscreen mode against his will. This is good (for security reasons).

I have an ASP.NET page, running in IE, that monitors several server jobs running at night. When an error occurs on a job, I have a popup window that opens with javascript, window.open(). The problem is, employees tend to have other applications, such as Netflix, running full screen and do not see the popup window notifying them of the error. I have javascript code on the popup page to continually set focus to itself, so it will blink in the taskbar, but Netflix covers the taskbar, so not helpful.
Currently using:
setInterval('window.focus()',500);
Is there a way to make a popup window in IE that will open over every other application?
No, you only have control over the browser and that is even limited, not the entire Desktop/Laptop.
The only way to overcome to other windows is using fullscreen=yes to make your window full screen. It's supported in IE only (MSDN docs) and Mozilla people hate it!
Otherwise you don't have access to OS level from the browser.
I am working on a Flash app that is 900x700 pixels. When viewed in misc. browsers at 1024x768, the browser chrome causes robs too much of the vertical space and the app appears in a window with a vertical scrollbar. Unacceptable.
The flash app will be launched via a link emailed to the viewers.
I'd like to avoid resizing the flash app and am wondering if there's a way to do the following via javascript, with no clicks involved:
maximize the current browser window
remove current window address bar and tabs / switch browser to full screen view (equivalent to pressing F11).
An alternative would be to resize the flash app vertically to match the browser canvas height to avoid scrolling. This may cause the app to become unreadable, so not the best approach in my case.
Thank you!
UPDATE: Seems that browser resizing and autoswitch to full screen won't work and neither will the flash app auto resize. What is the best approach then? And, some users may have browsers with toolbars or open a small browser window.
The only idea I have is to use javascript and display a message to users with small browser windows to pres F11 manually. The audience is executes and some may not even know what an F11 means...
There is no way to maximize the browser window to full screen with JavaScript. While this is unfortunate for your genuine requirement, it is considered a security restriction.

The window size can be altered by using:
window.moveTo(0, 0);
window.resizeTo(screen.availWidth, screen.availHeight);
To answer the question in the comment you made to your own post. Yes. You can have a button whose click handler does this
stage.displayState = StageDisplayState.FULL_SCREEN;
You can use JavaScript to open a new window (using window.open) and control the window that is opened (no address bar, etc). You can also control the size of the window (you can't maximize it, but you can get the users screen size, and set the window that same size).
Chrome 15, Firefox 10, and Safari 5.1 now provide APIs to programmatically trigger fullscreen mode. Fullscreen mode triggered this way provide events to detect fullscreen changes and CSS pseudo-classes for styling fullscreen elements. These APIs may present you with a more acceptable solution for those browsers.
