Need to export passwords to .csv format for bitwarden, but on-line advice says to go to "logins & Passwords" which is not to be found, only "Passwords" under "Settings", and no export option.

Am using a Lenovo laptop running Windows 11 and Firefox v.155.0.1 (latest). Have just purchased Bitwarden in order to have master password for security when computer goes for servicing etc. But cannot find the manner to generate csv file needed by Bitwarden. Any assistance would be much appreciated.
