Internet Explorer 9 Has Modified This Page To Prevent Cross-Site Scripting
Posted by in Problem Issue Error December 24, 2011 Leave a comment

My blog is running well on Firefox, Chrome and even Safari but when I switch to Internet Explorer (version 9), all Technorati Media banners usually become blank with just “#” and there is a popup at the bottom says: “internet explorer has modified this page to prevent cross-site scripting”

Not sure what’s wrong with the banners and why this just occurs in Internet Explorer. I understand that Cross-Site Scripting (XSS) attack is very dangerous for online visitors as they may be lost sensitive data such as cookies and sessions that stored in their browsers. And I truly think this feature is very useful for IE users as it may prevent them from being lost their user information.
