Is Funkify - Disability Simulator safe?

Funkify - Disability Simulator lets parent pages trigger clicks inside cross-origin iframes through its content script.

Funkify runs a content script on all pages and all frames to support its disability simulators. In subframes, that script listens for a FUNKIFY_IFRAME_CLICK postMessage and clicks the element at the supplied coordinates without checking the sender's origin or source.
