Hello,
Can a VPN be used on a per instance basis or once installed it has

used for all (browser) use?
A VPN is a network connection that (usually) appears just like
another network interface.
It can be configured to send all traffic elsewhere, or traffic
to a particular set of networks.
If you run one with proxy support, then you can have a
particular browser (with proxy support) use the VPN, and nothing
else.
Technology can be configured in a large number of ways.

Some web sites I want to continue visiting as I do now. Amazon.com
for example. There is at least one other site I sometimes want to
visit but am blocked because of my location. It is my understanding
that using a VPN to access this site allows my location and IP address
to be changed so I wouldn't be blocked.
Yes you can do this but exactly how you do it will depend on the VPN and
how much complexity you want to deal with.
The "guaranteed to work"(TM) method would be to setup one or more
proxies on virtual hosts and then route different websites to different
proxies. I don't remember the details but you do something with
proxy.pac to select different proxies for different destinations.
And then each virtual host can have a different route to the internet.
On a single host you can potentially do something similar but if the
proxy uses a different source address then you can use source based
routing. Many proxies allow binding to a source address.
You can also run one instance of the browser in a network namespace,
that way all traffic from that browser could be routed over the vpn
while other traffic goes directly - this avoids the complexity of
setting up a proxy but adds the complexity of setting up a network
namespace.

Hi Tim,
It looks like a big can of worms and way more complexity than I want to
deal with.
Thanks for the help.
Best regards,
