- Rated 5 out of 5by quonzo, 5 years agoSpoof Timezone, spoof WebRTC and CanvasBlocker will be the best antidetect extension ever!
Developer response
posted 5 years 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 - Rated 5 out of 5by mdaiurrto, 5 years ago
- Rated 4 out of 5by Firefox user 14428109, 5 years agoGreat extension!
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 5 years 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. - Rated 5 out of 5by Firefox user 15311590, 5 years agoThe most reliable canvas fingerprinting blocker available still even after years, blocks types HTML5 and ClientRect! Great job!

- Rated 5 out of 5by Maleficient, 5 years agoMister 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 :

I will check the file and include it. - Rated 2 out of 5by Harry Haller, 5 years agoUnfortunately, 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 5 years 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. - Rated 4 out of 5by Dewnan, 5 years agoI 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 5 years 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. - Rated 5 out of 5by Firefox user 13230603, 5 years ago
- Rated 5 out of 5by surrealisme, 5 years agoHello, 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 5 years 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. - Rated 5 out of 5by Thomas, 5 years agoDas 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 5 years 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. - Rated 5 out of 5by Filipo, 5 years ago
- Rated 2 out of 5by Firefox user 13579870, 5 years agoleider 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 5 years 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. - Rated 3 out of 5by Fraaggle, 5 years agoNice 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 5 years 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 - Rated 5 out of 5by Mark P, 5 years agoOne of the best Spoofing addon, Developer is excellent person.
