Opera v52.
All OK last night. Not this morning.
Yahoo login is fine, but any attempt to go to the mail pages gets the "too many redirects". Message text varies from mg.yahoo yada to guce.yahoo yada, yada
Cleared cookies no dice.
Managed to get in once with IE, but not since.
Nothing helpful on google.
And just to add to the "fun" Opera won't upgrade.
