I don't see any evidence of this happening in Firefox. Either it's more difficult or they just didn't bother, either way I'm happy.
Edit: Can't find much documentation on exactly how the anti-fingerprinting works, but this page implies that the browser blocks extension detection: https://support.mozilla.org/en-US/kb/trackers-and-scripts-fi...
From memory from working with these a couple of years ago:
Firefox extension asset URLs are random and long (there's a UUID in there iirc). The extension itself can discover its randomized base so that it can output its asset URLs, but webpage code can't.
