make pdf file occur in firefox window

for acrobat reader 7, you don’t need to install the reader plugin. It just copy the plugin file into firefox’s plugins directory. Remove it, nothing changes. The problem always troubling me is the pdf file always open outside of the browser window no matter whatever you set.
Thanks to The unofficial fedora FAQ, I know that I need to install evince and mozplugger. It works great!

By the way, this site also tell me to use ntfs-3g to mount my windows ntfs partition, not the old ones which were always coming with the kernel number.
