Hello, I hope you're doing well. Unfortunately, my Firefox account was still signed in on my old mobile phone, which is now being used by my father. He accidentally deleted all of my bookmarks, and I have completely lost access to them. To make matters worse, I do not have any offline backup of my bookmarks. I was wondering if there is any way for your team to restore the bookmarks associated with my account to a state from before December 31. Thank you very much for your time and assistance.
