After trying SSH Tunneling, probably you feel it is painful to change proxy settings manually every time. And maybe you have another proxy so you need a quick proxy changer. There are extensions to help us change the proxy settings by just a click. It is SwitchySharp for Chrome and Proxy Selector on Firefox. Of course, you may create different proxy configurations as many as possible if you have more than one. I will show you how to install and use it.
