I don’t see why you can’t use one browser for banking and another for other things? On mobile, some people even use apps that only interact with one bank. Or an app just for YouTube.

(I don’t use separate browsers, but I gave Facebook its own Chrome profile.)

A new browser would need to do one everyday thing really well to get part-time use. The question is what that is.

Financial service requirements have a habit of spreading into other websites. Imagine e.g. PayPal blocks their payment widget from working on other browsers. Suddenly shopping might be impossible with that browser. In fact, the current state is that PayPal will always require 2fa if you use Firefox, so this isn't particularly far fetched.

Because those banks have recently replaced SMS OTP with mobile app push confirmation dialog. But the bank's app does not want to work when there's any app installed on a smartphone not specifically whitelisted in a bank.

Everyone hates SMS OTP them here at HN, but here's an alternative.
