Until recently I have been able to use the chat feature just fine, but now I can't log in to chat. It seems that this feature is now relying on a cookie or web store at stackauth.com
.
As I'm blocking third-party cookies and have no intentions of doing otherwise it seems that I can't use chat any more.
Why has this change happened? And could it be undone?
Temporary fix:
If you need to chat NOW, both balpha and the only part of the help page that I didn't read have a solution:
Go to https://meta.stackoverflow.com/users/chat-stackexchange-login (or the same URL on any Stack Exchange site where you're logged in) and click the button.
FireFox
on that page. That qualifies as broken!;-)
