If you are using a proxy plug-in for browsers to anonymize your traffic, be aware that some websites are still able to determine your real IP address and identity by using Flash or Silverlight Chrome plug-ins.
How is that possible?
Those plug-ins enable a SPDY proxy inside Chrome. All HTTP and HTTPS requests are then forwarded in an encrypted manner to the respective proxy and the proxy will then execute the requests on behalf of you. BUT: Flash and Silverlight apps are built different and can not be forced to use the proxy. In fact they can perfectly ignore the proxy settings. Then HTTP(S) requests made by these apps will not go through the proxy and your real IP can be transmitted to the website - despite the protection of a proxy plug-in.
How can I disable Flash & Silverlight plug-ins with Chrome?
1. Open the following URL in Chrome: chrome://plugins, to open Chrome's plug-in settings pane.
2. Disable 'Adobe Flash Player'
3. Disable 'Silverlight' (in case it's installed)
