插件简介

查看插件说明、主要功能和适用场景。

This browser extension safeguards user privacy by preventing malicious scripts from using the HTML canvas element for user fingerprinting. It introduces slight changes to the data generated by the canvas element when specific methods are invoked, rendering it unusable for fingerprinting. In comparison to similar extensions, this one is lighter and employs a more efficient method to obstruct fingerprinting across all frame elements (top and subframes). The extension operates in three modes:

1. Random noise

2. Random noise (per page) to maintain a consistent identity within the current page session

3. Fixed noise to sustain a constant yet unique identity continuously

Key Features:

1. Minimal footprint fingerprint defender

Hält nicht, was es verspricht. Auf der folgenden Webseite kann man sehen, dass man trotzdem einen wieder erkennbaren Fingerabdruck hinterlässt, egal, was man in den Optionen einstellt: https://coveryourtracks.eff.org/ ------------------------------------------------------------------------------- Does not deliver what it promises. On the following website, you can see that you still leave a recognizable fingerprint, regardless of what you set in the options: https://coveryourtracks.eff.org/

No more fingerprinting on every single webpage that isn't dead html coding from 2008

I was using https://coveryourtracks.eff.org/ to test how unique my browser's fingerprinting was, and when I first installed this extension, nothing appeared to change, so I uninstalled it, checking the box that it didn't behave as expected. I then installed the Canvas Fingerprint Defender extension, which works pretty well. I then re-installed Canvas Blocker and disabled Canvas Fingerprint Defender and coveryourtracks gave the desired results, giving even fewer bits of fingerprinting than either extension alone. It could just be an artifact of how coveryourtracks reports things, but it is looking like Canvas Fingerprint Defender anonymizes something, which remains better-anonymized even after disabling it, which then allows Canvas Blocker to better defeat coveryourtracks? Whatever the metrics and tests, it shouldn't really matter how unique it is reported to be, since Canvas Blocker should be generating new randomized values every time, meaning that even if it is unique, they still can't track you due to it always changing. The two extensions do slightly different things, and are both quite good at what they do.

Просто работает

отлично работает,оно меняет сигнатуру canvas fingreprint'а при каждой перезагрузке страницы,а если отключить то у тебя на всех сайтах одна и та же сигнатура, можно отследить ну вы поняли.
