Set up Firefox Sync (recommended)
A Firefox account lets you sync your data and preferences (such as your bookmarks, history, passwords, open tabs, and installed add-ons) across all your devices. It's free to use. You will need to set up Firefox Sync before an upgrade. When you sign in to Firefox on your computer after an upgrade or on a new device, your customized profile will sync to the new browser version with no further intervention needed.
