I previously used QuickProxy addon for Firefox but found that it failed to load Youtube for me. Today I changed my proxyfier into FoxyProxy and it solved all my problems. Here is a brief tutorial of how to use it under Firefox.
After installing it, you need to add a proxy server. Here I conviently named the profile ‘Beyond the Wall”.
Next step is putting in the address of the proxy server. I use a ssh tunnel between the localhost and the remote host, so the address here is 127.0.0.1 and the port I designated under putty is 9000. Be sure to select “SOCKS proxy?” otherwise the page won’t load.
I don’t want to use this tunnel for all the sites, so I need to tell FoxyProxy to only proxify sites I want. Still under the new proxy server interface, add the patterns for the sites to visit.
I don’t know if configuring using this is totally secure and anonymous or not. If you know better ways to use ssh tunnel and Firefox, tell me.
