Okay, the error was in front of the keyboard.  When using the proxy
settings in Chrome (which uses the system proxy), I was following the
same protocol as in Firefox - and entering the details in http and
selecting to use for all protocols.  The answer was to enter for the
socks option only.  Then it works in Chrome.

Sadly, that has the consequence that when I fire up Firefox, Firefox
also uses that proxy - whether proxying in Firefox is enabled or not.
That's bad.  Loathe as I am to have a third browser installed, it
looks like I might have to use the TBB for secure browsing instead of
Chromium (which had been my plan.  Firefox is altogether safer and
easier to configure for a higher-level of safety without going torshit
crazy (and it's also useful to have a browser that stores some

So now I have the following questions.

1)  Can I use the TBB even though I have tor installed and running successfully?
2)  Is there a danger in having tor running even when I'm not using it?
3)  I was reading up on exit-point safety and apologies to the people
who spent time documenting it, but I didn't understand that well at
all.  I'm a native speaker and technically literate, so I'm concerned
other people might not understand it either.
4)  Do I need privoxy or obfusproxy?

It's https://check.torproject.org - which I referenced in my original.
