If I had a nice high CPU high RAM machine, you mean?

Envision the following scenario:
Alice wants to buy beeswax candles online. Because beeswax candles
burn so cleanly. However, she does not wish to transfer her credit
card information over Tor, or even JonDo, because she's heard of those
attacks against ssl, and it's not as if there's anything anonymous
about a typical credit card anyway. But while she is checking out
unanonymously, she also wants to do some last minute market research
to make sure she is getting top-of-the-line beeswax candles. Now, if
Alice can run multiple instances of Firefox or some other browser
simultaneously, then the unanonymous (or partially anonymized, with a
direct connection to the vendor but anonymous connections to third
party sites -- yes, I know if compare logs with the vendor, it's
probably not that anonymous) connection runs in one instance of the
browser, while her market research is conducted in a second totally
torified instance of the browser. This decreases the amount of
profiling information those advertisers get on her. Thus Alice can
switch back and forth between anonymous and unanonymous browsing
without having to go through the trouble of closing all her tabs and
the entire browser and restarting again, provided she has a decently
high CPU high RAM machine.

Now, I'm not on Windows, and, as the OS I'm in at the moment can't
even handle Firefox 4, I'm actually using a similar browser that's
close enough that it can still use Firefox 4 add-ons. Also, JonDoFox
makes running multiple instances of my non-Firefox quite easy: there's
a menu option for it. Anyway, that's not the problem. The problem is
that if I actually try to do it, this poor machine basically grinds to
a halt.

So instead, I get to play with the proxy switching interface. Or, if I
really want to browse anonymously on just one or two sites and
continue browsing anonymously elsewhere, I get to add said sites to
the "Global proxy exceptions", and remove them when I'm done.
