We found the bug. Firefox for Android needs 1-15sec of being alive to fetch the block list. So it might not work when you open the test page directly from another app.
We have another browser fix coming in. But as a workaround, keep Firefox open for a bit.
Even after multiple minutes of the browser being alive, I’m still seeing insecure requests to emSign Root TLS CA - G3 go through. Fennec Nightly build date 2026-10-21T09:22:54. AAA Certificate Services is now blocked though.
Ah sorry, I forgot Fennec was also the name of a fork so my comment was ambiguous. I meant it as the original Firefox for Android codename, not the fork. I’m running an official Mozilla build of Firefox for Android Nightly.
Edit to add: 2026-10-22T08:45:08 reports everything secure though. Thanks for all y’all’s work on this!

Fennec is not Firefox for Android but a fork. Please report to them.
