I did try clearing Cookies and Browser History with no effect. It seems Facebook must have changed something, as Opera 36 on Windows 10 no longer works properly on Facebook. But it does on my Windows XP SP3 machine (same browser Opera 36) .. I was trying to do a Repair of Opera and what ended up happening is it updated to Opera 62 .0.3331.18 .. I am running the 32 bit version on my Toshiba Windows 10 Home 64 System and Facebook now loads fine. I have no need for the 64 bit Opera at this time. I will add the User Agent Switcher as it may come in handy sometime.
