Hi! I am a longtime firefox user and I recently got a new computer. I installed as normal and signed in to my account, downloaded my favorite add-ons and was set. When I was done with my browsing session I closed the application. When I went to start it again my account had been un-synced and my add-ons nonexistent. I signed in again and downloaded the add-ons and when I restarted the application the same problem occurred.
