Start evaluation of deer park(firefox alpha)1

To check the interchangeability of extensions, I start to use deer park 1.

But frankly speaking, alpha version is actually alpha version.

My template of extension is not work well. Deer park 1 crashes after installing my extension.
(But next time I installed the same extension, it works. I do not know why.)

I am now writing a book for development of firefox extensions. It will take more time.
