Environment:
Operating System: Windows 10 PRO x64
Firefox version: Firefox Nightly 111.0a1 (2022-02-13) (64-bit)

Preconditions:
ETP set to STRICT
Clean profile

Steps to reproduce:

1. Navigate to: https://www.easyjet.com/en/
2. Attempt to perform account login.
3. Observe the result.

Expected Behavior:
Account login is successfully performed.

Actual Behavior:
An error message is shown.

Notes:

• Not reproducible with ETP STANDARD.
• Reproducible in PRIVATE Mode as well.
• Screenshot attached.

I can sign in without any problem with ETP strict. Do I need to be in a specific region?

It could be that I was testing from Romania. If VPN is set to the US, I get the same result, unable to sign into my test account. Could it be something with our account that shows this difference between ETP STRICT vs STANDARD?

Hmm, I can still log in after VPN to the US. It's unlikely to be account specific issue, but I can test with the test account if you can provide it to me.

I've sent an email with the credentials.

I can still log in successfully with the QA test account.

Tim, I think the Windows update version might have been the cause on my part. With the new update of the system, I can not reproduce the issue.

I see. Could we resolve this bug for now?

Sure, we can

Thanks.
