// Not all Chromium-based browsers support managed storage. Merely testing or
// exception handling in this case does NOT work: I don't why. The extension
// on Opera ends up in a non-sensical state, whereas vAPI become undefined out
// of nowhere. So only solution left is to test explicitly for Opera.
