I recently switched from Linux to Windows and installed Firefox on my new system. I signed in with the same Firefox Account that I had used on Linux, but none of my bookmarks, shortcuts, or other data have synced. It feels like a fresh Firefox setup. Here’s what I’ve tried so far: 1. Confirmed that I signed in with the same Firefox Account. 2. Verified that Sync is enabled for bookmarks, history, and other items on Windows. 3. Triggered manual sync multiple times, but nothing has appeared. Is there any way to check if my bookmarks were stored on the Firefox servers, and if so, how can I retrieve them?

Starting last night, Microsoft wants me to login with my username and password. However, it will not allow me to input those factors. I have Windows 11 and am using a new desktop cube made by KAMRUI. I detest the control Microsoft is forcing on me. Can I delete my MS account? I don't use their products. Also, I am disgusted by their manipulation and invasion of my privacy. What are my options, in this case?

Virusscanner warning supposedly from "Mozilla Firefox" On my laptop I get these fake warnings (see attachment). Every time Firefox is opened they appear. The virus scanner says there are no virussen. How do I get rid of this?
