I can log into Firefox, but if I try to click on nay other websites, the URL comes up, but nothing loads. I try to refresh the page, but the refresh 'circle' is greyed out and doesn't work. Then it's as if my mouse pointer is broken; I can't click on anything. Everything works fine in EDGE and other browsers. This seems to have happened after the last Firefox update. I have cleared my cache and data, and refreshed Firefox. So far, no good.
