(Archived) Anybody noticed probs with Genesis-based sites and Firefox plug-in?

Is it just a coincidence that the sites I've had problems with are based on the same WordPress framework? Or is there something I can do on my end to guide the Evernote clipper into finding the article rather than having to grab the entire page (sidebar, ads and all)?
