Hi, what happens when you try to access Facebook? If Firefox shows an error message in the tab, could you copy/paste the text of the error into a reply here.

Nothing shows up, and when I click on Home, my page, notifications or messenger...nothing happens..no messages.

Do you get the login form, and you sign in, and then it's blank from there? Or you sign in, you get the blue header bar, but the parts below that area missing?

Any difference in a private window (Command+Shift+P)?

On the log-in form, Facebook comes up in the https place but nothing else appears. I normally sign in from Firefox by clicking on Facebook in Bookmarks..same thing. Thanks for trying to help.
