Re: Firefox in two or multiple languages on one system

To find the language file, right-click (control-click) on the Firefox 
app/Show Package Contents/Contents/Resources. I would guess that you 
could d/l a Spanish localization of FF, remove the "es.lproj" from the 
Resources folder and place it inside the same in the English version. 
Now whether or not this will work I can't say, but you'll let us know, 
right? ;-)
