Since my browser doesn't allow for third-party cookies (which is a deliberate choice) I have to try to log into chat via StackExchange.com -- however, repeated attempts simply yield a blank page (no HTML or CSS) that reads this error:
No referer was present - this may be due to a browser setting
Why am I getting this error? How can I work around it? If the answer could include an option that doesn't require me to allow third-party cookies, that would be awesome.
For completeness: I'm using Firefox Portable on Windows 7. I do not have any ad blocker running, though I do use an extension that masks my IP address.
