None of this works for me; I've manually installed Adobe Flash, disabled my firewall, disabled my addons, made certain everything was the current version, etc. - no luck. My problem is that not only can I not comment I ALSO CANNOT access my account, nor save videos to my playlist. Notice in one picture I have my firewall/addons disabled then for contrast - I have a picture showing my firewall/addons enabled.
