Thanks R'as!
I wasn't sure what to use and have been using proxies from proxy-list.org so far that had at least SSL support.
The sites I access are all SSL protected too, but still wasn't sure whether or not the proxy could read the packets and sniff them: could be someone has a script that does that specifically for SSL?

Tried VPN first, but this place doesn't seem to like UK sites in general and the VPN is in the UK.

Will use TOR then, if that's safer. Thanks!
