Trying to install Firefox, please help

I have a laptop runing windows Vista
I downloaded firefox.dmg and used UltraISO to extract the folder. I FTP the folder to the frontrow applications folder on the ATV. I reboot the ATV and go to the applications menu, i see the firefox icon, i click on it to install and the screen goes black, nothing happens. I want to install firefox, what iam i doing wrong.
