What encoding is the server/page says it's in?

Firefox mainly go with the encoding the server/page tells it to do. [1]

The encoding is not specified. Just text/html.

Then your depending on sniffing and won't get utf-8 unless the first package of the page contains a unicode character. You SHOULD have encoding specified either in the http header or in the http head (<meta charset="utf-8">), else it will be a gamble if there will be one or not.
