Safari Password Export

Safari uses Keychain.

Apple offers no bulk password export function for Keychain.

Might want to ask for that as an enhancement: Product Feedback - Apple

Poke around the ‘net too, and see if any of the available third-party export options offer a functional export:

https://1password.community/discussion/30286/mrcs-convert-to-1password-utility-mrc-converter-suite

I have used neither, and can make no representations of their function or security.

Try suggestions given in this article.

I am not sure Passwords can be exported to Firefox browser.

You can import passwords from Firefox.

• Imported passwords go into your iCloud Keychain, so you can autofill login information on websites.
