===================================
Instead of completely blocking canvas fingerprinting, Canvas Defender add-on creates a unique and persistent noise that hides your real canvas fingerprint. This add-on protects you while browsing both in normal and private mode. With Canvas Defender you are in control to drop your spoofed identity anytime.

Canvas Defender add-on is strongly recommended for users of all multilogin tools except MultiLoginApp, which already has in-built Canvas Fingerprint spoofing option.
