Boosting Privoxy's Filtering Capabilities with Customised Filters

[Faxopita]

Canvas fingerprinting and WebRTC blockers written by Black Rider and available here. Both tested successfully on my configuration.

Code:

FILTER: CanvasBlocker
s@(\w\.getImageData\((.*?)\));|(\w\.toDataURL\((.*?)\));@@

Test here.

Code:

FILTER: WebRTCBlocker
s@<head(.*?)>@<head$1>\n<script>function NoWebRTC(e){return 1}
window.RTCPeerConnection=NoWebRTC;
window.webkitRTCPeerConnection=NoWebRTC;
window.mozRTCPeerConnection=NoWebRTC;</script>\n@i

Test here.

Code to block Javascript-written keyloggers available here. Website in French, but you can just grab the code.

Don't forget to activate these filters in user.action file.
