Following a restart, Firefox has installed this icon on my desktop: "Linguistic handbook feeds backup.opml", with the Firefox picture. All it does it is take one to a browser page opening the file on my C drive, and saying blankly: Firefox Live Bookmarks. (Incidentally I cannot see this file listed anywhere under Mozilla in Programs or Programs , so I suppose it is nested in something else.) I assume I can delete this without damaging Firefox for all eternity, but I am curious to know how it got onto my desktop. I assume the "linguistic handbook" is not actually what it says but something to do with the many languages Firefox is translated into, yes ? - or does it really deal with catenatives, anaphora, kernel clauses, retorts (et al.) used as a test of auxiliary status, or whatever ?
