The simplest way is by using Firefox Sync. Firefox Sync transfers your bookmarks, browsing history, passwords, and open tabs. On your old Laptop Open Firefox, menu > and look for Sign in to Sync or your email address/Sync status. If you're already signed in, click your email address. If not read [[Access Mozilla services with a Mozilla account]] In Sync settings, choose what data you want [[How do I choose what information to sync on Firefox?]] Wait to complete the sync. On your new Laptop Sign In to Sync using the exact same Mozilla account. Firefox will automatically start downloading and syncing all your data.
