Trying to follow USGS Recent Quakes website and WeatherUnderground websites, to name only these two site-sets for now, ONLY the landmass locations are shown, NO quake locations are shown. Only happening since the "global IT "glitch"". This is ONLY happening with Firefox, all the same websites show as intended in Google Chrome. PLUS using the mouse scrolling wheel no longer zooms in or out using a Logitech wireless mouse with Unifying Dongle. Any help out there? Thanks, Oldheart
