When a web browser window is opened, only the menu options should be visible to users. I don't want other toolbars. Also, is it possible to blocking users add toolbar from the menu that will be visible to them. IE and Firefox please.

Thanks in advance

PopUps PopOpen PopUnder are blocked by most
Anything like this would get you downgraded in searches, and have a negative impact on your site traffic
Use layers within your code to give the effect of popups without the stigma of popups

didnt bother importing all the styles, but it runs as is, the styles just color code the buttons

Sorry. I think i should be a bit more spesific.

I mean address bar, standard buttons etc. should be disabled or removed when a new windows is opened.

Please, read detailed description of the methode open() of the object window, eg. here.
I suppose that what you request is something like:

window.open("./page.html", "the_name",  "left=350, top=25, width=800, height=500, menubar=no, toolbar=no, location=no, status=no, resizable=no")

In some discusion it is shown that you can change the attributes of curent window


but I never got success with those commands.


kiosk mode
at the machine, change the shortcuts to
Iexplore -k
Opera -k
unsure about firefox, but there is the 'public fox' plugin that is supposed to work in the same way
