    The most reliable canvas fingerprinting blocker available still even after years, blocks types HTML5 and ClientRect! Great job!

    Mister Korbinian Kapsner, hello,

    Here is the French translation of CanvaBlocker ; in uft8 with WinMerge ; I hope there is no problem with the accents used in the French language.

    It was long and very difficult, because you don't have to master a language, but computer science.
    Computer dictionaries are not pedagogical ; the definitions are often worse than the word itself.

    Sorry, for taking so long to finish the full translation.

    Link valid for 30 days ; click on the French words :

    Hello, interested in the check mark "Share persistent randomness between domains", if you remove it, I realized that each domain will have different data, if you turn it on, a warning that there will be a leak, the question arose, what can domain x request from domain y? and what result will it get if this checkbox is disabled and the request is received

    You can read the background of this flag in https://github.com/kkapsner/CanvasBlocker/issues/290

    To be short: this flag makes you 100% unique and trackable across all domains. The use case for this was not to prevent fingerprinting but to disguise. Not quite the main focus of CanvasBlocker but it seemed useful for some folks.

    In general I highly discourage you to from using this flag unless you clearly understand it and it suits your need. If you use it you have to reset your persistent random number generator quite frequently.

    PS: domain x cannot request any additional data from domain y but the faking will add the same "randomness" to the API readouts and this information can be used to be tracked.

    Das Plugin ist sehr gut und tut, was es vorgibt.

    Wenn ich die beschriebenen Fehler anschaue, würde ich anregen in den Einstellungen den Default-Blockiermodus auf "vortäuschen" zu setzen. Das Problem: Sehr viele Seiten setzen heute auf Canvas unterschiedlichen Arten. Mit der Default-Einstellung werden die Seiten stillschweigend nicht geladen. Im Fragemodus wird man permanent belästigt: Selbst WordPress-Seiten setzen auf Canvas.

    Ev. wäre eine Testseite hilfreich, wo man die Einstellung testen kann. Im Paranoiden Modus ist "amiunique" nicht mehr aussagekräftig bzw. lädt nicht mehr sauber. Im Modus "vortäuschen" auch nicht mehr wirklich, da die Testapp das Gefühl hat, sie kriege echte Daten. Eine Konfig, dass man grad noch arbeiten kann aber genügend blockiert wird, ist nicht ganze einfach.

    Danke für die Vorschläge. Der Standardblockiermodus ist schon "vortäuschen" und unter https://canvasblocker.kkapsner.de/test/ gibt es Testseiten für die einzelnen APIs. Wenn Sie noch weitere Vorschläge oder Verbesserungen haben, können Sie diese gerne unter https://github.com/kkapsner/CanvasBlocker/issues hinterlegen.

    Hi. I've been using this add-on for a while now. Is it still relevant with the new Firefox update which includes anti-fingerprinting? thanks

    Yes, it still has purpose. See https://github.com/kkapsner/CanvasBlocker/issues/349 for further information.
