Hi! I have many years of syncing bookmarks, settings and passwords, but 2 months ago, when I installed a new version of Firefox on Windows Pro 10, I can't do that. The instructions on your website do not help me. I go to my account in the browser, sync, but the bookmarks are empty!!!! I want my passwords, bookmarks and settings! Bad browser! AND I can't log in to my account for help support!!! The password does not match. You preset a link to change password, I menu it with both big and small letters, but it does not fit!!! 100 attempts!!!!!!!
