AFAIK, there are some sort of alliance between google and firefox. Isn't it a little bit strange that google offers its adsense preview tool for IE only?

The IE preview tool was out before the major "alliance" of the Firefox developers moving over to Google. I'm sure they have a FF version in the works. To be honest, the preview tools needs a lot of improvment, hopefully a FF version will be better.
