The same issue is discussed at https://addons.mozilla.org/de/firefox/addon/canvasblocker/reviews/1141570/ and https://github.com/kkapsner/CanvasBlocker/issues/154

In short: it fine to have these sites to report a unique fingerprint as long as the fingerprint changes (which is the case in the default CB settings). You can open up the console (Ctrl + Shift + K) and have a look at the actual fingerprint. There you will see that the protected fingerprints change with each reload.

Regarding support: github is mainly a code managing service (you can look at the complete source code and history of CB there). But it also offers a requirement and bug tracking feature. As I am only one person I have no time to give individual email (or even phone) support. On github some helping angels can support me. Also it provides an overview of already asked questions and open issues so other people with the same issue can see that it is known and/or what the solution is.

    Helps stop sites and corporations from tracking your internet activity. It works with no issues.

    Unfortunately 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...)

    Damages 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.

    ウェブサイトが全く正常に動作しないことはほとんどありませんが、一部のウェブサイトでは非常に動作が遅くなることがあります。
    性能の低いコンピュータでこれを使用するのはおすすめしません。

    Underrated extension, everyone who values privacy should use it.
