Bibtex Extension for Firefox
 

Now I've Googled this, but didn't get anything that seemed useful, so I'm coming to Google No. 2 :-p. Does anyone know of a Firefox Extension that can obtain the bibliography information of a page? So for instance, if I was viewing a W3C Recommendation that I linked from the w3.org website, is there a piece of software that'll have/catch all the usual "referencing" fields and put it in Bibtex format? Would be quite handy methinks.
