When Fox-Fire is played from hidden, can it only target the battlefield it is on because it 'chooses'?

Ruling: Yes, when Fox-Fire is played from hidden, it can only target the battlefield it is on because it chooses a target.

Nuances:

• The limitation applies to effects that choose, based on the FAQ
• You don't need to see the word "choose" explicitly written on the card for it to be considered a choice
• Choosing a game object is targeting rulewise, though some cards may say "choose" without issuing targeting
• The FAQ is the most up-to-date source for this ruling
