Maybe a translation problem?I don't speak Portuguese, but that path sounds much more like
what is called in English:C:\Program Files|Mozilla FirefoxThats the location of the program files, not the profile. The defaults 
folder you have found is the location of default files that are used in 
creating new profiles.I've never used Vista, so I can't be real specific, but Application Data 
is hidden under 2K and XP, so it must be hidden also on Vista. I'm sure 
you know this, and I'm sure you have enabled hidden files and folders to 
be shown, so I am at a loss as to why you can't find the profile.Lee
