Unfortunately these days you need to be a bit more weary when searching the net. Tor is a powerful way to secure your internet connection. Chrome is an awesome browser with powerful extension capabilities. Join these together, and you have an awesome privacy machine. Also, if you live in Australia, there is an impending great privacy violation in regards to the great firewall of Australia. This will probably help you get past it.
1. Get Tor
What is tor? It's is ridiculously hard to explain so I wont. So try Here and Here to get an explanation.
Get your download here.
Install it and use all the default setups. A great guide, again from the Tor website is found here.
2. Get Proxy Switchy! Extension for Google Chrome.
Proxy Switchy is an excellent extension for Google Chrome which lets you seamlessly manage your proxies. Due to the nature of proxies, Tor connections are generally slower than your direct connection, so you don't want to be jumping through hoops every time you want your information to be private.
Get Proxy Switchy Here.
If you used the standard Tor setup, your proxy details are as follows:
HTTP Proxy: localhost
Port: 8118
Click on Proxy Switchy options and fill in as following.
All done.
3.Get your privacy on!
Now every time you want your privacy kept, click on the Switchy Proxy setting and select Tor.
Hope this helps, and yes this will probably help you get past the great firewall of Australia.
