Version 1.4 (2016-Mar-05) • extension was (unnecessarily) trying to patch functions in a cross-origin frame (like hangouts frame in GMail, Disqus frame in several sites, etc.)

Such websites do this by painting an image on a hidden HTML element and then taking a snapshot of it and posting the snapshot back to themselves.

Because the exact pixel values in the drawn canvas can differ subtly from one set of hardware to another, these websites can use those differences to distinguish between visitors as well as to recognize specific visitors from one visit to the next.

Which is what tracking cookies are normally used for, except that cookies may be disabled or deleted or avoided by browsing in Incognito mode, whereas to avoid canvas fingerprinting you need to use a tool like canvasfingerprintblock.
