Hi, The people who answer questions here, for the most part, are other users volunteering their time (like me), not Mozilla employees or developers. Mozilla does not offer phone support. Can you share more detail about the issue you're experiencing? Without more detail, there's not much we can do to help. When posting questions, it's helpful to include information such as your operating system, browser version, specific error messages, are you using private browsing etc, and the steps you've taken to try solve the issue. This kind of context allows the community members to provide a more accurate and effective solution. Looking forward to your update!
