Making Your browser Dual Screen

If you want to make the browser can open 2 pages at a time like in the picture below:

To make your browser as the picture above, you simply use the script from javascript.
Following steps:
1. Open your browser (To test I use mozilla firefox browser).

2. Enter the following javascript into your browser address:

javascript:g4pt3k=location.href;int3rnet=prompt('Masukkan%20URL%201',g4pt3k);brows3r=prompt('Masukkan%20URL%202',int3rnet);if(int3rnet&&brows3r){F1nd='\n';F1nd+='\n';F1nd+='';with(document){write(F1nd);void(close())}}else{void(null)}

3. If the message "Enter the URL 1", the contents of the URL you want.
Fill with (Example): http://www.yahoo.com

4. If the message "Enter the URL 2", the contents of the URL you want.
Fill with (Example): http://indo-webster.blogspot.com/

Now you have a browser with dual screen.
