This is not exactly your approach, but you may disable the navigation panel of any window using plain javascript. Just set window.menubar and window.toolbar visibility to false as follows,

window.menubar.visible = false ;
window.toolbar.visible = false ;

---

Update:

Changing the menubar and toolbar visibility of an existing window seems to violate security protocols. (https://developer.mozilla.org/en/DOM/window.menubar)

Therefore the only real way is to open a new window with menubar and toolbar set to "no" in the first place:

window.open(url,name,"menubar=no,toolbar=no[, additional options]",true) ;

If you set the replace argument (the last argument) to true the new window should also inherit the history of the window it was opened in.

Check https://developer.mozilla.org/en/DOM/window.open and http://msdn.microsoft.com/en-us/library/ms536651(VS.85).aspx for reference.
