Hi, Firefox community, A website aimed at providing regional utility services, such as online utility bill inquiries and payments. One of the services is, integrating Fesco Bill, which offers users the ability to check their utility bills online. Ensure that the service works seamlessly on Firefox, My questions are: Are there specific steps or tools recommended to test the compatibility of such embedded tools with Firefox? How can I optimize external service integrations to ensure they load efficiently and maintain privacy standards for Firefox users? Any advice or guidance from the community would be greatly appreciated! Thanks in advance for your help. Best regards,
