When importing logins and notes and URL from Chrome to Firefox, why the latter doesn't bring notes and read double URLs?

All of my notes are gone and if similar URLs are doubled.

Sharing one screenshot, since I cannot share another due to privacy (until a Mozilla dev team asks for it directly without sharing it on public platform).

Hello, I'm currently using a Macbook Air, Early 2014, that still works perfectly fine for my needs. But it runs with OS X 10.9.5 and Firefox 78.15.0esr, that unfortunately can no longer be updated. That wouldn't be a problem to me since I do a very limited use of the computer, but now I'm getting the message "Your Firefox may start to have problems on January 14, 2025 since updates are not available for this OS". What should I do if I still want to use this device with Firefox to browse the internet? If it is impossible to keep using Firefox, any suggestions for an alternative browser that may still work? Safari is no longer an option. Thanks a lot for any and all replies
