I tested this extension that I've been using for a long time on the turnstile page and it got through, fwiw. I think it's a bit more subtle than how resistfingerprinting works but not sure what the privacy tradeoff is.

Looks cool. And I wonder why I'd run this over JSshelter. It appears to do the same thing, no?

Thanks for the report, I've been running this for a long time.
