I've only had the new laptop for 2 weeks, it was working OK (except for new Outlook and cannot revert to old when I try) and suddenly today, I can't access F/fox any way I try) Bing constantly hijacks Firefox when I try to load it; cannot re-set firefox as default from Bing page; attempts to re-set default from M/S Edge continually revert to Bing. (I've been using firefox for over 20 years and DO NOT want to change.) Please help!!!!! Please help!!!!!!!!!!!!!!!!
