This from gmail is just pathetic. 1) Don't tell people to switch browsers. 2) When you ignore no.1, please make sure that the button actually works, so that I can dismiss the notification.

gmail Video description: a notification from Google encouraging the user (me) to switch browser to Chrome. Repeated clicks on the "Don't switch" button does nothing, and the notification can not be dismissed.
