Thank you! I am going to try your fix shortly. - Just before I logged back into the forum, I tried just turning off "Private Browsing" in the Settings/Protection and that seemed to work. THANKS, AGAIN! - Feeling relieved. It's funny how much I rely on Facebook to keep in touch with my family who are scattered, literally, all over the globe and the panic I felt when I thought I might, even temporarily, lose touch.
Same problem since this morning. Facebook works on MS Edge just fine but not on Google Chrome or Mozilla Firefox unless I turn OFF KIS. - - I hope there is a fix coming for this . . soon. - - Not comfortable spending time on Facebook without security and I have to remember to turn it back on when I'm done.
