I will be staying in a country that has Internet censorship in the near future (it's one of these countries: https://secure.wikimedia.org/wikipedia/en/wiki/Internet_censorship#Substantial ) and I would like to ask for freeware software recommendations that will allow me to access blocked websites while being able to use the normal, no-proxy connection for unblocked websites (for faster access), preferably by allowing to add the blocked websites to a whitelist.
Although my preferred browser is Opera, I am also looking into solutions with Chrome or Firefox. The OS I will be using is Windows 7.
Also preferable, but not required, is if the proxy has fast access speed (ping and bandwidth).
Note: I already tried the proxy software, Freegate with the Firefox proxy management extension, FoxyProxy (has a whitelist that allows a blocked website to be accessed thru proxy while allowing the rest to use the normal, non-proxy connection) but I get this error page when trying to access a website thru proxy: http://note.dit-inc.us/swprompt.html , which basically states that the servers gives out higher priority to China and Iran-based users (understandably), making only a limited number of sites available to Non-China or Non-Iran-based users. As I will not be staying in China or Iran, Freegate will be of limited usefulness to me.
