I have found what causes the error message to be displayed. But the value for the string is boolean with no option to change it i.e. i have a choice of true or false. Somehow i need to change this string to display a message e.g. "This is a restricted website!!!". Obviously FireFox looks up this string when a restricted website is accessed so its not like i can simply create a new string, neither can i create a string with the same name it simply only allows true or false.
This string below:
browser.xul.error_pages.enabled
Anyone got any ideas on that?
Cheers for the continued help
