Since nightly and release are affected, beta will likely be affected too.

I see a failing captcha in the devtools when clicking on the button for the first time:

https://api-web.royalmail.com/mailpieces/v3/{{removed: tracking number}}/events

{
  "httpCode": "401",
  "httpMessage": "Unauthorized",
  "moreInformation": "captcha validation failed",
  "errors": [
    {
      "errorCode": "E0015",
      "errorDescription": "Access denied",
      "errorCause": "Invalid or expired captcha token",
      "errorResolution": "Please request for a new captcha token"
    }
  ]
}

The second time seems to consistently succeed. It doesn't seem to be related to blocking resources, but I couldn't figure out another root cause.

For me this doesn't even work in normal mode with ETP off. I keep seeing NS_ERROR_NET_INTERRUPTED when trying to talk to the api-web.royalmail.com host.

Moving to Site reports based on comment #3 and resetting triage.

Looks like we need a tracking number in order to test this.

The tracking number from the screenshot on the GitHub issue is TQ632570345GB but unfortunately that tracking number doesn't seem to work at all in Chrome or Firefox at this point.

Does anyone have a tracking number that can be used to reproduce a Firefox-specific issue at this point?

Oh, huh - the tracking number wasn't getting me a useful page on Firefox or Chrome on desktop, but it does work properly in Firefox-on-Android - I get to a page that says "Delivered" along with other tracking info.

It works for me in normal mode as well as private browsing mode as well. I tested Firefox release 144 as well as Nightly 146 on my Pixel 10 Pro XL (using Private Browsing mode in both, visiting https://www.royalmail.com/track-your-item and pasting in TQ632570345GB as the tracking number)

So whatever the bug was here, it seems to have been fixed.
