in the case of the corporate proxy, you delegate trust for the duration 
of your use of the browser at that location.

So I would expect some UI indication that is basically permanently 
indicating this is happening, which is why I previously suggested the 
frame could be a way to do it.

There's also a class of proxy that we haven't been considering much 
here, that is possibly the most wide-spread:

Localhost proxies for products like endpoint AV.
