posted 4 months agoThe language of the addon is controlled by Firefox and should be the same like the other UI of Firefox (if CB is translated to that language). If this does not work properly pleas comment at https://github.com/kkapsner/CanvasBlocker/issues/479 with the language your Firefox is and the language that is displayed instead.- by Cercion, 5 months agoRated 5 out of 5
- by The GodFather, 5 months agoRated 5 out of 5This is a very helpful extension. Could you add a whitelist button directly in the app menu ?
Developer response
posted 5 months agoThere is a whitelist button in the "fingerprint" menu. In https://github.com/kkapsner/CanvasBlocker/issues/330 is a screenshot of how to find it. Developer response
posted 5 months agoYes - the people translating on https://crowdin.com/project/canvasblocker are very helpful. Thanks to you all.- by quonzo, 5 months agoRated 5 out of 5Spoof Timezone, spoof WebRTC and CanvasBlocker will be the best antidetect extension ever!
Developer response
posted 5 months agoSpoofing the timezone is not trivial (see https://github.com/kkapsner/CanvasBlocker/issues/464). WebRTC might be worth a look. Please open an request at https://github.com/kkapsner/CanvasBlocker/issues - by mdaiurrto, 5 months agoRated 5 out of 5

I would like to submit a suggestion, would it be possible to allow shortcut key to duplicate a tab in another profile?Developer response
posted 6 months agoI'm not sure what you mean by "in another profile". Please open an issue at https://github.com/kkapsner/CanvasBlocker/issues with an exact description of your suggestion/request. - by Firefox user 15311590, 6 months agoRated 5 out of 5The most reliable canvas fingerprinting blocker available still even after years, blocks types HTML5 and ClientRect! Great job!

- by Maleficient, 7 months agoRated 5 out of 5Mister 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 :

posted 7 months agoThank you for your contribution. I will check the file and include it. - by Harry Haller, 7 months agoRated 2 out of 5Unfortunately, after installing CanvasBlocker in FF 74.0 (64-Bit), Twitter doesn't work any more. Maybe, there would be a setting to prevent this, but sorry, this should be set by default, since Twitter is a very common network. Also other common sites like translate.google.com don't work any more.

posted 7 months agoBoth sites work fine for me with default settings. Please open an issue at https://github.com/kkapsner/CanvasBlocker/issues with all your details so we can sort this problem out.
There we can communication better and you can track the progress of your problem. - by Dewnan, 7 months agoRated 4 out of 5I have a conflict between Privacy Badger and CanvasBlocker when starting FF or restarting with my restart_firefox.uc.js script, it stops at loading ex: google.com (home page), I press F5 then it loads.
Disabling Privacy Badger on google solves it... anyone else have this problem?Developer response
posted 7 months agoThis kind of behaviour was already seen but could not be reproduced in FF 73. Please add your system information at https://github.com/kkapsner/CanvasBlocker/issues/388. This issue is currently closed but can be reopened. - by Firefox user 13230603, 7 months agoRated 5 out of 5
- by surrealisme, 7 months agoRated 5 out of 5Hello, 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
Developer response
posted 7 months agoYou 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. - by Thomas, 8 months agoRated 5 out of 5Das 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.Developer response
posted 7 months agoDanke 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. - by Filipo, 8 months agoRated 5 out of 5
- by Firefox user 13579870, 8 months agoRated 2 out of 5leider kaum nutzbar! Der Hesteller bietet eine Whitelist an, aber die bringt absolut nichts, das Kästchen kann man Internet Seiten füllen wie man will, aber sie werden trotzdem Gnadenlos geblockt, es funktioniert dann absolut nichts, gerade die SUchmaschinenseite: swisscows.ch. Daher wieder deinstalliert, den mit so etwas kann man nicht arbeiten!
Developer response
posted 8 months agoIch kann Ihr Problem mit swisscows.ch leider nicht reproduzieren. Bitte öffnen Sie ein Ticket bei https://github.com/kkapsner/CanvasBlocker/issues, damit wir das Problem eingrenzen und lösen können. Die Kommunikationsmöglichkeit hier ist einfach zu stark eingeschränkt.
In meinen Tests funktioniert auch die Whitelist mit dem Eintrag "swisscows.ch". Wobei in so einem Fall besser ein Seiten-spezifischer Blockiermodus eingestellt wird.
PS: Die Bezeichnung "Hersteller" ist etwas falsch. Ich bin eine Person, die dieses Addon in der Freizeit entwickelt. - by Fraaggle, 8 months agoRated 3 out of 5Nice addon, but why it needs reading and changing privacy settings? This is new after the last update. Why you need that now?
Developer response
posted 8 months agoAs discussed in https://github.com/kkapsner/CanvasBlocker/issues/438:
The access to the privacy setting is needed to display the notice for privacy.resistFingerprinting. So it's not that important but unfortunately I cannot make it optional.
CB only reads that and does not write any privacy settings: https://github.com/kkapsner/CanvasBlocker/search?q=%22browser.privacy%22&unscoped_q=%22browser.privacy%22 - by Mark P, 9 months agoRated 5 out of 5One of the best Spoofing addon, Developer is excellent person.
