Framekiller - Framekiller Limitations

Framekiller Limitations

Client-side JavaScript solution relies on the end-user's browser enforcing their own security. This makes it a beneficial, but unreliable, means of disallowing your page to be embedded in other pages. The following situations may render the script above useless:

• The user agent does not support JavaScript.
• The user agent supports JavaScript but the user has turned support off.
• The user agent's JavaScript support is flawed or partially implemented.
• The user agent's behavior is modified by a virus or plug-in (possibly without the user's knowledge) in a way that undermines the framekiller script.
