As of this morning (3/31/16) I'm not able to log on to facebook via firefox on my laptop - I see various line by line entries that come from the usual facebook login page, but no graphics like the usual page shows. I tried to log on via Internet Explorer, and was able to log on and get the usual looking facebook down loads as usual. What's changed with Firefox so that I can't get my usual facebook download? I've changed no laptop settings, so what's going on?
