For both Passwords’ and Cookies’ dialogs, I don’t think that filtering using the SearchBar could be a so basic action that it should be displayed by default (I don’t have enough passwords for needing browsing, and I usually don’t look to a specific cookie).

So, let’s make the SearchBar of each of these dialogs toggleable.
