- Install the LastPass browser extension in Firefox, and use the Import option to transfer your existed saved passwords and logins to LastPass.
- In the Firefox menu under ‘Preferences’, under ‘Logins and Passwords’, uncheck the option to ‘Ask to save logins and passwords for websites’ so that LastPass can take over filling your credentials on all our favorite sites.
