Removing Firefox Star Icon and Bookmark Icon

I am building an application which has requirements stating that all browser features must be disabled. (It's a test taking application and they are worried about security/cheating.)

I popup a new window so that I can make it fullscreen, disable the menu bar, tool bar etc. However Firefox still has two icons remaining that I can't figure out how to disable. The 'Page' icon and the 'Bookmark' star icon are still on even when I call w开发者_如何学运维indow.open with location=no. Here is the window.open command:

window.open("filename", "test", "fullscreen=yes,status=no,toolbar=no,location=no,menu=no,directories=no,scrollbars=yes"); 

Is there anything I can do about this?

From the MDC documentation for window.open():

Mozilla and Firefox users can force new windows to always render the location bar by setting dom.disable_window_open_feature.location to true in about:config or in their user.js file

In Firefox 3, dom.disable_window_open_feature.location now defaults to true, forcing the presence of the Location Bar much like in IE7.

This was done to help thwart phishing exploits. You're better off (your users are better off) leaving it enabled, even if you have control over the machines on which the browser is running.

You should really be designing your application such that knowing or bookmarking the URL won't help would-be cheaters. For instance: don't accept an answer to a question when an answer has been previously submitted.

If you don't have control of the computer the user is taking the test on, there's nothing you can do (and opening a full screen window won't prevent cheating for savvy users, either).

If you do have control over the computer or can instruct the user to install an application, you'd be best suited by building an actual application with embedded WebKit or Gecko.
