How do I fix Facebook working in Safari on a MAC?
For over a month Facebook has not worked properly on my i-Mac or MacBook Pro both running macOS Sierra 10.12.6. Facebook works fine on my IOS devices - i-Phone6 and i-Pad. I also have no problem using Firefox to enter Facebook on my i-Mac or MacBook Pro.
I have logged out and logged back on to Facebook and Safari on my Mac's and nothing changed. I also changed the password on Facebook and no change.
How do I fix this?
iMac (27-inch, Late 2013), macOS Sierra (10.12.6)
