Using this now and the 1st thing I noticed was that I had to re-login into all my sites, which in of itself is not such a big deal. My only question is will using this feature have any negative impact? I guess I'll keep using it for a while and see if I notice any problems. I'm mainly concerned about how this could impact sites that you need to log into. Some sites use a sub-domain to login which redirects you back to the top-level domain. That is where I suspect I could have an issue and I'd test it now if only I could recall a site which used that at the moment.
