- Rated 1 out of 5Not good. Had partial protection before installing add-on. This add-on makes my browser 100% unique.
Developer response
posted 2 years agoYes, in the standard settings of CB the fingerprint that is produced with CB is quite unique but not persistent. That means the browser itself (and therefore you) cannot be indentified by it. (The same issue was reportet on github: https://github.com/kkapsner/CanvasBlocker/issues/154 - if you want further informations you can explore the issues there or post a new one.)
Also there are a lot of options which change the behaviour of CB (just mark the expert mode). If you want a less unique fingerprint you can use the "white" random number generator which will result in fingerprints similar to those of the Tor browser. - Rated 5 out of 5Hey there, take a look at Browser Console to know about your add-on's error. Keep up a good work.

- Rated 5 out of 5seemingly good help to browse with more privacy, complex work.
since update from 17dec, blocks all web-pages :(Developer response
posted 2 years agoI currently face weird problems. Please open an issue at https://github.com/kkapsner/CanvasBlocker/issues with all your details (versions, settings, etc.) so that I can find the root cause.
EDIT: please try version 0.4.4 - Rated 2 out of 5Description claims there is a whitelist option but...there is no visible way to see, let alone edit, such a list.
Developer response
posted 2 years agoThe whitelisting was hidden by the last release. You can whitelist by setting the desired blocking mode for the URL specifically. If you want to whitelist an URL just give it an "allow everything". You can still whitelist a site from the notifications. I should definitely clarify the description...
Adding an URL specific block mode:
go to options, click on the triangle next to the blocking mode, enter the domain you want to whitelist, click on the plus, now you can set the blocking mode for the domain.
PS: you can still enter something in the white list by checking expert mode, open the export settings page and entering something in the whitelist field.
EDIT: Is the screenshot of the settings not explanatory enough?
EDIT2: It's easier for us to communicate on github. If you have any questions - just open an issue. Here the communication is slow and not relyable.
EDIT3: please try version 0.4.4 - there the whitelist is available again. - Rated 1 out of 5reverted to 0.4.2 as 0.4.3 (all) is blocking pages, either when firefox starting with last session, or login to AMO

posted 2 years agoCan you please file an issue at https://github.com/kkapsner/CanvasBlocker/issues with more details. I already know that there are problem but I'm not able to spot them because I never had a reproduction scenario.
EDIT: Have you tried any of the Beta versions? https://github.com/kkapsner/CanvasBlocker/releases/
EDIT: Please try version 0.4.4 - Rated 5 out of 5This is a fantastic add-on for users who are concerned about privacy while surfing the web because it efficiently detects and blocks/fakes canvas fingerprinting. I use CB on all my machines with Firefox (52-ESR and >57) and it supplements nicely other privacy-related add-ons. Based on my own experience, I can also confirm that it receives superb support by a very helpful and responsive developer. Clearly a must-have five-star addon!
- Rated 5 out of 5Funktioniert bei richtiger Einstellung korrekt. Schneller support. Danke!
Works fine if settings are correct. Fast response. Thanks!Developer response
posted 2 years agoI will look into this issue (progress can be seen here: https://github.com/kkapsner/CanvasBlocker/issues/161). The faking is working fine on https://browserleaks.com/canvas
EDIT: They are using a very big canvas (400 000 pixels) to do the fingerprinting. It works fine if you disable the "Maximal fake size" ("Maximale Vortäuschgröße") setting. I will adjust the recommendation accordingly. - Rated 5 out of 5Very configurable and useful tool if you don't want to be easily fingerprinted. In 1000 years it will be common knowledge to install in every Firefox. For now, we're the lucky ones that learned about it.
- Rated 5 out of 5Seems to cause issues with direct links to images. When this addon is activated only a white page is displayed instead when the domain is loaded for the first time. Deactivating the addon and reloading the link makes the image show up correctly. Afterwards the addon can be re-enabled again without making the image disappear again (only lasts for the session, restarting firefox breaks it again).
FF ESR 52.5.0
Edit:
The issue has been resolved, the author created a separate version. Great support!Developer response
posted 2 years agoThis issue was already reported to me. But I'm not able to reproduce it on my end. Please create a new issue on github with the informations to reproduce the problem (Firefox version, installed Addons, CB settings, URL to the not working image and if the problem is still present when a fresh profile is used): https://github.com/kkapsner/CanvasBlocker/issues/new - Rated 5 out of 5本質的です
