WebBrowser Script Blocking

I have created a Web Browser using ieframe.oca and mshtml.oca (IE Webbrowser Control). I have used Mozilla for many years, and there are 2 features in Mozilla that I consider a must: Multiple Tabs and Selective Scrip Blocking. I find it difficult to understand why Microsoft has never considered such a feature, or why no one offers a selective script blocker Add-on for Internet Explorer, and I have not found a way to implement this feature in my new browser. Up to IE version 6, there was a streaming function available that you could stream the Web page into a string, modify it to suit, and then output the string to the HTML decoder. But since Version 7 this no longer appears to be available.

Any suggestions? Even though this new Web Browser is fast and efficient, it is unlikely that I will ever make extensive use of it unless I can solve this particular problem.
