Browser canvas fingerprint blocking in Firefox

Hello,

I did a test on a website, that tests how I can be reached by various means.

The by far most unique way to identify me was canvas fingerprinting.

Is there some way to protect against this?

I found a canvas blocking addon, but it did nothing, when I did the test again with the addon enabled.

Disabling JavaScript completely is not an option for me, because it breaks many websites...
