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).

1. Limited Customization: Thunderbird lacks advanced customization options for user interface elements, which can make it feel outdated. A blast of modern UI updates would enhance user experience.
2. Performance Issues: It can become slow and unresponsive when handling large email archives, causing frustration.
3. Lack of Native Calendar Integration: The absence of seamless calendar features is a notable drawback compared to modern email clients.
4. Inconsistent Updates: Irregular updates often leave users waiting for critical fixes and new features.
5. No Built-in Encryption: Users must rely on add-ons for email encryption, which isn't beginner-friendly.
6. Poor Mobile Compatibility: Thunderbird does not offer an official mobile app like whiteout survival gift codes, limiting its usability on the go.
7. Add-on Dependency: Many essential features depend on third-party add-ons, which may not always stay updated.
8. Search Functionality: The search tool is basic and struggles to efficiently sift through extensive email libraries.
9. Syncing Issues: Problems often arise when syncing with third-party email services, leading to errors.
10. Clunky Setup Process: Setting up accounts and configuring settings can be a challenge for new users.
11. Limited Support for Collaboration Tools: Thunderbird doesn't integrate well with modern team collaboration platforms.
12. Static Design: The interface design is static and could use a blast of innovation to compete with newer email clients.
