Bug 1518799: Show a custom page on startup on Nightly on a specific date. r=Gijs We want to show an informative message about dedicated profiles per channel to users of Nightly on a specific date. We currently only have the ability to do this when the version changes. This adds the ability to show a page once on startup on a specific date. This will probably be backed out past that date.
