Firefox doesn't need extensions to handle the password and bookmark imports, it can do those automatically. I saw someone suggest you create a folder in your bookmarks that is your open tabs, bookmark each tab as you close them, import passwords and bookmarks, and open that folder for a relatively painless migration.

Do not rely on the built-in password managers to keep your passwords safe. Use a purpose-built one like Bitwarden to generate unique ones, save and complete them, agnostic to the browser. Virtually every stealer out there can easily grab the built-in password db's content.
