New features/Beta questionnaire

The questionnaire for Beta and New features uses the same 3 possible answers to the question 'why are you leaving the Beta?'/'Why are you turning off the new features?', in Prefswitch-survey-answer-whyoff-hard ("The features were too hard to use."), Prefswitch-survey-answer-whyoff-didntwork ("The features did not function properly.") and Prefswitch-survey-answer-whyoff-notpredictable ("The features did not perform predictably."). But the answers should be in the singular for Beta and plural for new features. Even in English they look a bit off.

 Done mwr:66541.

Incidentally, shouldn't these have been fuzzied?

I don't think it was enough reason to fuzzy.
