Comment (by acat):

 Thanks! It now works with the steps I mentioned, but the issue is still
 present with `privacy.resistFingerprinting = true`. More concretely, I can
 reproduce if I enable that pref and restart the browser, and then continue
 with the steps from the ticket description.

 I think it may be simply because `navigator.userAgent` is spoofed. Maybe
 you could use `browser.runtime.getBrowserInfo()`, which always reports the
 right version?
