Hi Russel - well, we can't whitelist all red cookies, right? Doesn't this defeat the purpose of cookie?
Also, I believe Safari history may be the source of these issues.
I always tell Safari to "clear history but keep website data." Even so, when I subsequently try to log into Twitter, Facebook etc. the websites often think I'm registering a new device
Yep, it just happened again. I did "clear history but keep website data" and suddenly Twitter can't recognize my device. I just whitelisted both "ga" and "gat" - are either of those cookies "tracking" cookies?
