Opera Software has developed a new version for its browser, Opera 7. The scope of this version, called "Bork Edition" is to make all Microsoft MSN web-pages display "Muppet Language".

"This is a joke. However, we are trying to make an important point. The success of the Web depends on software and Web site developers behaving well and rising above corporate rivalry," said Mary Lambert, desktop product line manager at Opera.

This version is made as a reply of how Microsoft created a CSS, that worked only on Internet Explorer (but even on this browser had an error).
