RecipeFox is guaranteed to work only for those sites that have a current definition file specifically created for them, currently 230+ individual sites are supported. As RecipeFox works only with Firefox, make sure that you have installed the most recent versions of that browser, Java (32-bit only even with a 64-bit OS), RecipeFox and the current RecipeFox definitions file list and installed them in that order. If that fails to work, contact the RecipeFox Support Forum at http://recipetools.sourceforge.net/phpBB3/viewforum.php?f=4 You will need to register as a member but the support team are helpful and you should get a speedy response if you provide the site name where you had attempted to obtain a recipe and at least one sample recipe URL.
