I've been using FireFox for a long time. My account is installed on two computers. The operating system of one is windows 8.1 (from work) and the other is windows 10. (from home) On December 7 or 8, 2020, my login list was suddenly deleted while I was working on my account with windows 8.1. I turned SYNC back on, but I couldn't get any of my recordings.

When I opened the same Firefox on my windows 10 computer at home, my login list was erased in less than 5 seconds.

I followed all the procedures on your help page. My login list is automatically erased when SYNC is on. I tried many times. It automatically erased my login list that I created from backup every time SYNC is on.

I request your help from Mozilla and Firefox authorities and review my account if necessary. I would like to see and use my November 2022 login list the same way if possible.

Thank you for your support

I'll say this any Work computer is not yours to do as you please as the IT has full access to your computer unless you save your data/file to a USB. You need to talk to your IT helpdesk about this issue that your having. One shouldn't use their work computer to sync to their home computer - this is asking for trouble if they wipe clean then everything is gone. Leaving your personal login saved on your work computer beyond the work login your giving them free access to all your online accounts.
