> Every time I install an extension I wonder what’s going to happen to my banking info if an update ever gets hijacked. This is a much better solution than turning all my extensions off and on when I visit financial websites.

Extensions already contain a whitelist of what domains they are allowed to interact with. It's shown when you first install the extension and at any time you can see it later by looking at the extension in the settings.

And a better version of this feature would involve a UI where you can select which extensions can access which pages, like Safari (and Orion, which is based on WebKit) does.
