I think we should have a mechanism to keep a list of "sites that need extra trust". Browser should warn about all sites whose url seems to be mimicking them.

I think we should have a mechanism to keep a list of "sites that need extra trust". Browser should warn about all sites whose url seems to be mimicking them. These would be all the sites on which you think you need extra amount of trust. Say all sites where you do financial transactions, and ones like gmail which are used for identity verification.
