posted 7 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.

posted 8 days agoA unique fingerprint is not a bad thing if it changes: https://canvasblocker.kkapsner.de/faq/#uniqueFingerprint- Rated 2 out of 5by blackSP, 9 days agoChecked before and after installing/activating this extension trying all profiles and see zero improvement in my identification score on several fingerprinting sites like coveryourtracks.eff.org and amiunique.org. Benefit of the doubt after reading dev's comment that it works anyway. Can't find any proof of that though.

posted 8 days agoYou need to check the details of the fingerprinting sites. Depending on your settings you can have a unique fingerprint - but this is not a bad thing if it changes: https://canvasblocker.kkapsner.de/faq/#uniqueFingerprint - Rated 5 out of 5by Firefox user 17902463, 13 days ago

posted a month agoUnfortunately the workers do not offer an API to interact with them from a web extension. That's why I opened https://bugzilla.mozilla.org/show_bug.cgi?id=1636977.
So I do not see a maintainable way to handle this issue. (The only would be to disable workers...) - Rated 5 out of 5by Firefox user 18605300, 4 months ago

- Rated 4 out of 5by Andre Bell, 5 months agoDamages Linkedin, as other comments here and on github have noted. Enable 'Advanced' settings and add Linkedin.com to the whitelist and all is well again. Do NOT alter any other settings unless you want your browser vulnerable to the noted exploit mentioned in the FAQ.
