Delete com.apple.Safari.plist file and test.

Empty the Trash.

Quit all applications.

Option click the "Go" menu in the Finder menu bar.

Select "Library" from the drop down.

Library > Preferences > com.apple.Safari.plist

Right click on it and select "Move it to Trash".

Restart. Relaunch Safari.

If this doesn’t help, “Put Back” the com.apple.Safari.plist

Right click on the Trash icon in the Dock and select “Open”.

Did you maybe hide your Favorites bar, and you only think you deleted them? Try Shift-Command-B and see if they reappear. If not, follow dominic's advice.

User's library folder is hidden by default.

Hold the keyboard option key down and click the "Go" menu in the Finder menu bar.

From the dropdown select "Library".
