Yeah, kind of depends on the context, from the dictionary:
foxed adj.
Discolored with yellowish-brown stains: "Their set of George Eliot was foxed and buckled by the rain" (John Cheever).
[Perhaps from the color of foxes.]
In Japanese history there is also the talk about fox ghosts possessing humans, so it could also be intepreted as "bewitched".
Edit: Also - FOXGLOVE: The name "foxglove" came from the words "folk's glove." Folks referred to little people, or faeries. One legend says that faeries gave the blossoms to foxes to wear as gloves so they would not get caught raiding the chicken coop. According to another legend, if you picked foxglove, you would offend the faeries. And if the faeries stole your baby, the juice of the foxglove would help to get it back. In some stories, foxglove appears as a faery's hat. Foxglove can sometimes heal and sometimes hurt. It is a poisonous plant, but it is also used as medicine to treat heart disease.
