Rated 5 out of 5 stars

Something happened overnight. I cannot get Thunderbird to authenticate access to my Calendar accounts.

Instead, I get routed to a Google help page about enabling cookies.

There's no indication of what to do.

Coming here has helped - but this isn't apparent - would be very useful to have an alert from either T-bird or Provider
