Does the problem persist when using a browser under the new account?

Yes, problem still there after logging in under a new guest account. Almost all the default Safari bookmarks offered (incl Apple, Yahoo, Wikipedia, Google Maps) were similarly unable to load then, although some sites like CNN, and the New York Times did work, same as they also do when I'm normally logged in my usual account.

I've also tried: booting in safe mode. Removing start up items. Saying a Hail Mary.

In Console, the system logs show the following thing over and over, around the time my trouble started. This "...FileDeleter ... got CFURL error..."  message repeats many many times over a few hour time span:

Nov 20 15:50:26 unknown001ff34e6908 PubSubAgent[18045]: FileDeleter: got CFURL error -10

Here's the log immediately preceding the beginning of that message:
