Thanks for this. The free Lastpass password organizer has a check to quickly see if any domains in your saved sites was compromised and then will check all email addresses in your account. Mine only came up with Adobe, which I already knew and was just a mailing list (no login)so we are ok.
However I will go through this list and look for the suggested chrome extension also
Thanks for posting this

There is a Chrome extension by Jamie Hoyle, based on Fillipo Valsorda's work (#1 above), that let's you check a website just by visiting it. A customizable pop-up informs you of any Heartbleed vulnerability plus other info.

EDIT: @Rick Grunwald - Pardon my omission. :-(
