It seems there might be some confusion here. As of my last update in January 2022, Mozilla, the company behind popular products like the Firefox web browser, had not announced any shutdown of separate websites. However, companies may change their strategies or services over time, so it's possible that there have been updates since then.
If you're referring to Mozilla shutting down specific websites or services, it would be helpful to know which website or service you're specifically asking about so I can provide more accurate information.
