Prevent redirects from transmitting+storing cookies+identifiers
I've been using RequestPolicy for so long I'd not realized that redirects have been getting more and more transparent. In Firefox 4/5, the loading indications are impossible to differentiate between redirects and 3rd party loads.
There does not appear to be any obvious about:config options to enable more prompting either. We may have to dig into the RequestPolicy source to see how they do this.
Redirect notification is important if we're going to try to keep 3rd party cookies disabled (or dual-keyed). If redirects are 100% transparent, there's little point in disabling 3rd party cookies.
NoScript has some options for notifying in the case of JS redirects. We'll probably want to enable those options in TBB, too.
