- Rated 5 out of 5by Firefox user 12596004, 8 years agoVery 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 5by Firefox user 12636919, 8 years agoSeems 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 8 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 5by areafix, 8 years ago

- Rated 5 out of 5by Nicholas Valentine, 8 years agoGreat extension, I really like the look of the icon in the address bar.
- Rated 2 out of 5by DarseZ, 8 years agoApologies, but this is an honest question: What would be the purpose of the add-on having access to 'all website data' such as banking/email login information?
Developer response
posted 8 years agoYou can look at the code (either at https://github.com/kkapsner/CanvasBlocker/ of you can download the xpi-file, change the extension to zip and look at the content). It does not store any private information or sends anything to a server.
UPDATE: I just realized I did not answer the question. The addon does not need access to login information (and does not use it). But there is no techical difference between the information the addon needs access to (the canvas and JS that are used for fingerprinting) and other information. I would gladly only take the permission to access the information that I only need - it's just not possible. - Rated 5 out of 5by Firefox user 9809896, 8 years agoVery good add-on
It would be bery nice if this great add-on also could portect against font fingerprinting. - Rated 5 out of 5by Firefox user 13357032, 8 years ago

Please check the link below:

is positive for Canvas Defender and ScriptSafe for Chrome.
With CanvasBlocker the icon briefly appears and disappears immediately.

I can insert some links but privately.Developer response
posted 8 years agoThanks for your finding. The faking is working fine - just the display of the icon is confused by this site. This will be fixed in the next release (see https://github.com/kkapsner/CanvasBlocker/issues/149 for reference - btw it's much easier for us to communicate on github via issues than AMO)
Since this is a minor issue there will not be a release for this alone. - Rated 5 out of 5by Firefox user 13433799, 8 years ago

posted 8 years agoPlease recheck your Firefox version and try to add it again. Version 0.4.2 should also run with Firefox 52.4.1 - Rated 5 out of 5by Anonymous, 8 years ago
