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.

Thank you very much for sharing keylogger blocker, I think I get some ideas from that, I can write a better version of it, and a better version of Canvas Blocker.

The CanvasBlocker you shared above is a nice solution for all web browser, it is sad that my version only works on Firefox and til now I still have no solution to make it works on Chrome.

I have some interesting filters to boost user privacy too, just check: http://www.prxbx.com/forums/showthread.p...7#pid18507
