Facebook used to be stable so while I was writing something, I could open other tabs to research things and go back to facebook and pick up where I was. SOMETHING HAPPENED some months ago, maybe a year (more?) and now I only have a short window to return BEFORE THE TAB REFRESHES and FLUSHES WHAT I WAS WORKING ON, DOWN THE TOILET! Is FACEBOOK OR MOZILLA DOING THIS AND CAN IT BE STOPPED!!!!
