Research direction
Investigate how Resemble.js renders difference images, particularly in about:blank windows. Check Firefox's handling of popup windows and image loading. Look at the source code for canvas or img element usage. Reproduce the issue in Firefox and compare with Chrome. Search for similar Firefox bugs regarding about:blank and image display.
