How do I fix Facebook working in Safari on a MAC?

Ok ..

You may have a third party Safari extension or plug-in installed that's causing a conflict with Facebook.

Troubleshooting help here > If Safari is slow, stops responding, quits unexpectedly, or has other issues - Apple Support

That has been causing problems with Facebook. Try going to Safari/Preferences/Extensions and disabling it when you want to access Facebook.

Do you have the Dashlane extension installed?

Hi,

"I also changed the password on Facebook and no change."

"For over a month Facebook has not worked properly on my i-Mac or MacBook Pro"

You were able to change your password but could you please give us more details about, "not worked properly"?

Thanks!

You are welcome.
