Especially after I am on FBook . If I use fbook I do all the aforementioned, close the browser completely then reopen. I really have nothing to hide but, I am a private person. Am I wasting my time and or is there some better method to maintain a "clean" desktop? I don't use Tor because I simply don't need it. I've tweaked the bejeesus out of FF configuration, use ublock origins and umatrix; just recently restarted https everywhere.
