Did some searching to no avail. Does anybody know if there is a Firefox plugin or GreaseMonkey script that, when you're on an external site that is linked to from HN, adds a link to the HN commentary for that page? For example I'm on http://supercoolbitcoinnews.example.com/omg-another-bitcoin-article and somebody has posted the url to HN, the plugin/script adds a clickable link somewhere obvious on the page so I know that there is a) already an article on HN and b) can easily go to HN and read the comments there.
Thanks. Still no luck, don't use Chrome day to day, and the original GreaseMonkey script that it's based on doesn't seem to work for me. Might give it a crack myself some time.
