Why isn't my FireFox opening?
I did this update thing for it & now it won't open. What's going on?

The second response seems to be the way to go. Uninstall FireFox and download via IE, then reinstall.

The computer thinks it is a invalid program and opening file. Uninstall it and use internet explorer to try the Full download of the browser again.
