Not all site have the support for secure browsing thus rendering this useless.
Now what I do to actually bypass the filters are using proxies. You might be wondering to yourself, "WTF, all proxies are blocked!" Well you thought wrong =D
Not all proxies are blocked, just the popular ones.
Also, run you're own proxy. You can apply for an appspot domain and run a python caching script which in turn can be used as a proxy.
