Browser Privacy Extension

Screenshots

Hopefully improves your privacy

I have no idea how it may be useful for you, but all those tracking annoys me enough to make this experiment.

Made it years ago as a proof-of-concept. Now it's open source!

Feel free to contribute!

Canvas protection technique was based on Canvas Defender extension. Other ones I made by trial and error by myself. I'm very proud of my WebGL and fonts replacement tech - it's insane!

Test

I test on https://browserleaks.com and https://fingerprintjs.com/demo (you need to clear cookies & local storage of this site to see difference) by https://github.com/Valve/fingerprintjs2
