about:config
network.security.esni.enabled = true

PAC-script - any and enabled in settings.

They can't work at the same time.

test hangs up and nothing happens.

Can you attach the PAC-script?

This could be important for the DoH rollout. P1 to look at this during the next release.

ESNI isn't enabled at the moment, and we don't need it for the rollout. P2.

Priority: P1 → P2

The issue is still present on some Firefox 74/75 installations.

ESNI is removed, so close this bug.
