Not really - Paypal was doing it via their browser toolbar ages ago, back when toolbars were still a thing. They stopped offering this functionality back in 2009, I think. That said, it's not particularly common at US banks despite being a horrifically useful feature (Bank of America has it, but I'm not aware of anyone else).

I'm excited that I can hop on and use Privacy but it seems like it's more of a feature than a product.

Virtual cards from Citi and masked cards from Abine.com

Virtual citi cards are nice in theory, but the web app to make them it pretty cumbersome to use, and the desktop app to do it just feels super icky. They also have short expiration limits, so it's not great to use for subscriptions where you ideally set and forget.

Edit: the web app for Citi was also a flash app last time I checked (few months ago). That plus them not supporting 2FA for every login makes me not use it.
