It seems that Google Chrome doesn't keep my "allow all cookies" settings (dev 5.0.322.2) anymore.
Google's sites keep on showing:
Your browser's cookie functionality is turned off. Please turn it on. [?]
but every I perform the prescribed steps, Chrome doesn't keep the configuration!
update: I've deleted
~/.config/google-chrome/Default/Preferences and restarted with a clean state. Now it seems to work.
