We are encountering an issue where the links in the emails function properly and redirecting to us to the exact pages on Google Chrome, Microsoft Edge but they do not work on Firefox. We are getting this error "HTTP Status: 404 (not found)".
Supoort team said, upon debugged more and find our tracking domain is giving the same error so your tracking domain is not working.

But upon reviewing the sending domain, it has been confirmed as "Passed", and the tracking domain is also valid.

After reviewing your ticket, I noticed that your tracking domain had multiple DNS records. This can cause issues with resolving requests, regardless of the browser or version being used. For instance, if there are three DNS entries for a single tracking domain, each entry has a 33.3% chance of resolving a request. In your case, Firefox accessed the incorrect DNS entry, which was cached. However, if you remove the incorrect DNS entries, Firefox should work properly once the DNS cache is cleared.
