As of 7/10/2024, I cannot sign in to ATT.com via Firefox. Other web browsers work correctly. The site generates a "902" error (proprietary). In the console, I see a failure to load 2 scripts: Loading failed for the <script> with source “https://signin.att.com/static/thirdparty/adobe/detm-container-hdr.js”. LrrController:33:2 Loading failed for the <script> with source “https://signin.att.com/static/thirdparty/adobe/detm-container-ftr.js”. Note that I can click that link in the console and each of those scripts loads. I have tried disabling tracking protection for the site as well as disabling the adblocker.
