Note ...
Facebook has changed again without notice.
Take a look at your URL (top box on your screen). If you see "http" or only "www" instead of "https", you do NOT have a secure session and can be hacked.
Go to ---> Account Settings (Account Settings) ---> Security (Security) ---> click Change or Edit.
Check (Cheque) box (Secure Browsing), click Save (Save).
You see again your URL will open https
Thank you.
