I sort of do this at home, sometimes my squid proxy is not available
on my home network. What I do to automatically work around this is
have the proxy configuration file on the local laptop file system
e.g. /var/proxy_script/proxy.pac then in the firefox proxy
configuration point the browser at this proxy script using:

file:///var/proxy_script/proxy.pac

in the proxy.pac I have:

function FindProxyForURL(url, host)
{
  var proxy_str = "PROXY 192.168.1.1:3128; DIRECT";
  return proxy_str;
}

When you have a proxy available it will be used. If the proxy is not
available then firefox will just spend ages loading pages initially
but once it has decided that the proxy is dead then pages load as per
normal. Every now and then firefox will take a while to load a page
as it decides to retry the proxy but overall you should have a hitch
free surfing session. I cannot remember the last time I tweaked my
proxy settings after putting this solution in place.
