When you clear the cookies of a website and reopen it, it will change. This means that the canvas doesn't change every minute, but changes according to the cookies. Different websites' cookies provide different canvases. As for why it isn't changed to change once every ten minutes, I don't know either. The developers need to provide the answer. |

I have cookie autdelete extension. Every time i close the website cookies get deleted. And as i said i tried closing/reopening website. Also fingerprint protection should randomize reply for every answer, not every minute or ten minutes. Starting from maybe 7 years ago, where no browser had fingerprint protection, and fingerprinting was relativelly new topic, there was already an early extensions for that, and they set the standards. |

@FaFre Can we so something about that to make it reliable? Is it gecko's own antifingerprint technology? Or it is WebLibre's implementation? I dont really like using too many extensions, and i guess others too. The more functions browser covers in a desired way, the less we'd rely on extension solutions. For example latest implementation of url cleaning was spot on. |

Well, for fingerprinting there is no ideal way. Every tracking provider works differently, and for most of them we don't know how the data is processed. All we can do is provide good defaults that make sense. For example, if you wear sunglasses at night, facial recognition might not work on you — however, you will probably be the only person in the area who wears sunglasses at night. Having too aggressive settings will make you traceable as well. The same as staying anonymous in real life, you don't want to look too different from the people around you. So when visiting websites, the same applies. You don't want to look different from other regular visitors to the website. When visiting Reddit, for example, where there is a large international user base, the requirements are different from visiting the site of your local telco provider, whose users probably all share the local timezone and language. Having too harsh settings there would make you stand out and possibly make you traceable. But again, every one of the thousands of tracking providers out there works differently, and their detection methods might change daily. When doing research about fingerprinting, I did not want to make WebLibre stand out. IronFox, Vanadium, and other browsers do not trigger a refresh of the canvas on every reload either, so I kept WebLibre the same. This could quickly become a trackable variable: "Oh, that's the guy who changes his shirt every time he goes around a corner." However, WebLibre gives the freedom to adjust all possible parameters, and you can set fingerprinting parameters according to your use cases. |

If you visit https://browserleaks.com/canvas you can test canvas fingerprint protection. If protection works every new test you should see different strings if unique numbers. However, i tried reloading, and closing/opening webpage, and its every time the same unique identificator, even though i have canvas randomization enabled in settings. Extensions in other hand do the job.
