Localhost:3000 in chrome seems to block cookies with no apparent change

I see the following message on every single Meteor application that I am using in Chrome when on localhost:3000.

You are running a browser with no localStorage or userData support. Logging in from one tab will not cause another tab to be logged in.

Does anybody else have the same issues?

This started over the weekend and remains until now. I am using Chrome, but have not consciously noticed any updates or changed any extensions. Only my localhost is affected.

I don’t have any new extensions and no sites defined under ‘clear on exit’ or ‘block’

But my user login details are now lost every time I make changes to the client and the browser reloades the app in development.

Does anyone here using Meteor have the same issues?
