According to [this question][1] on Meta.StackOverflow:

> Changes to the question will now notify users who have favorited the
> question. Notifications include comments to the question, edits, new
> answers, and edits to answers. This is a way to get updates on
> questions that you yourself didn't ask.

The answer does not explicitly state where the notifications appear, although I assume they would appear in my Stack Exchange inbox. However, I have not once received a single notification for any of the questions I have favorited.

Cross referencing my [inbox][2] and [favorites][3], I can confirm that there are no notifications for any activity from my favorites.

Is my account glitched?
