by 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 4 out of 5by Firefox user 12814982, 6 hours agoAn sich ein wirklich klasse AddOn, was Webseiten definitiv zu schaffen macht.
Leider bremmst es den Browser je nach Seite extrem aus.
Gerade Karten-Webseiten wie z.B. Google Maps sind teilweise unbenutzbar, wenn der CanvasBlocker zuschlägt.
Der Blocker von Firefox selbst, ist hier etwas harmloser, dafür aber auch von der Block-Qualität schlechter. - Rated 5 out of 5by Rinshun, 3 days ago

- Rated 4 out of 5by B00T987, a month agoI love this extension! However its a bit hard to use, because you have to uninstall, and reinstall the extension to open up the easy to use settings picker. If you change your settings as often as I do, if not then this is an easy 5/5 extension.

- Rated 4 out of 5by AnoniM0US3, a month agothe addon prevents "youtube comment search" addon from working
is there a way to fix this, without having to turn canvasblocker off each time?
or even better: can i block or unblock each element separately, until i find the culprit? (the way "NoScript" addon visualized this is very beginner userfriendly)
thank you - Rated 5 out of 5by Firefox user 18369793, a month ago
