It would be really helpful if Firefox could synch all the passwords stored in web browsers into one place ... a little like importing bookmarks. So not just keychain, but also MS edge, Chrome etc.
Firefox would convert so many Apple diehards by adding more support of things like iCloud passwords and Keychain. Please make this easier for me and tons of other people!
I was floored when I looked for a solution for this and realized it's not offered by Mozilla. It makes using FF a pain in the. Importing a passwords file from Safari is not sufficient: anytime a new password is saved or changed in Safari means that password will not work with FF. So frustrating.
