Comment (by arthuredelstein):

 Replying to [comment:2 qbi]:
 > If I set {{{network.cookie.cookieBehavior}}} to 0 (allow all cookies),
 the Like button works again.

 Thanks for reporting this -- I can confirm that. I examined the request
 headers for the POST observed by Isis in comment:1 under two different
 pref settings:

 * When `network.cookie.cookieBehavior` is 0, the header entry
 `Authorization: Bearer AAAAAAAAAAAAAAAAAAAAA[...]` is included (data
 omitted in brackets)
 * When `network.cookie.cookieBehavior` is 1, that Auth header entry is
 missing, and the response includes "message: "Bad Authentication data."

 So the next step is to investigate why Firefox does this and also check if
 Firefox 52 has the same problem.
