Success and thanks! Rated 5 out of 5 stars
Right, I tried to solve the puzzle but failed! If I cut/paste the xpi link I get a page full of gunk, but don't know how to save it to a proper xpi file. And also could not find the download link on the blog page. (Update - got it installed using html trickery which I tried to paste into my other "reviews", but that naturally failed! Hopefully admin removes them soon).
