Why Mozilla won't develop "Firefox Frame" as IE Plugins? And what the Google strategy.

Last week, Google Chrome Frame announced.

This week, Mozilla representatives response such "evil" product...
Mark Shaver, Mitchell Baker wrote in their blogs. They listed the integrity problems when used GCF. Firefox Dev. Team ables to create IETab, and also I believe that Firefox Frame can be developed if she wanna do.

If you know Firefox product, why you install "Firefox Frame" instead of install a organic application?
Same question can be apply any application that is "browser within browser"...



GCF is a toxicant for IE family

Basically, GCF break the connection to IE native render/javascript engine finally only a application layout remained.
In my mind, GCF just a part of Google Wave Project. G Wave reject IE family to access because they using incomplete web standard. It refreshed all the people conversation behavior in Internet to like more human being. Users are highly dependent on conversation and welcome to setup their computer to use G Wave. If you use G Wave, you must sign agreement to kick IE out.
When people is used to work on G Wave and have a period to understand the advantage on Chrome. They will shift to native Chrome Browser.

I appreciate this alternative way to kill M$IE.
At the same time, I also afraid the future of Firefox when Chrome support extension feature. Walk the old path like Netscape.
