well.. you can use one of the web proxys all over the net.
you will have to pay a bit.. to get https access.. but.. they let you control the cookies... and all the history going to show is that you were going to the proxy's URL.. everything else.. is encrypted between you and the proxy
their are other options on the net .. for secture connection using a labtop as well.. that secure the connection.. so you can use public networks .. and if anyone is on the line .. well they get crap that is 128 bit encrypted
good luck
