Browser Compatibilty

[k4kashifb]

hi!
I am a student of BS and developing a web page as a semester assignment in PHP+JavaSCript
My assignment is to protect the publish content i.e. not allow the user to copy/print/save/save as of the text page.
So far, i have done with the following
1- disable the right click event on Internet Explorer6.0 to avoid the following
a- Select all
b- print
c- copy
2- Disable all the menu so that a user cannot do the following
a- File->Save
b- File->Save as
c- File->Print
d- View->Source(Possibly to avoid the copy of the content by viewing the HTML source code)

All of the above have been done by using JavaScript.

Now here comes my pain ---->
When i start testing the code, it works fine with Internet Explorer 6.0 but when i test it with Mozilla FireFox, the

javascript doesn't work. What i want is to make it to all web browser compatible. or is there any other technique to do the

same work  in a good way

Any helping material in this regard will be highly appreciated.
Thanking in advance.

There is no way to do this at all... any attempts to protect anything shown in the browser are a waste of time.  I hope this isn't a university-level course.  If the browser can display it, the user can get to it.
