You can read Thunderbird mbox files from the command line using a Python script that leverages the standard library's mailbox module to parse and decode email headers and plaintext bodies.

To extract email headers from a local Thunderbird profile, point a Python parsing script to your mbox file path to decode and read specific headers such as From, Date, and Subject.

Yes, you can parse multiple mbox messages at once by iterating through the mbox file with Python's standard mailbox module to extract headers and plain-text bodies from single or multiple messages.

No external Python packages are needed to parse Thunderbird emails; the script requires only Python 3 and uses the standard library's mailbox module to handle mbox file parsing and header decoding.

This Python mbox parsing approach is designed for local Thunderbird profiles on Unix-like systems, so it is not explicitly tested or supported for extracting emails on Windows environments.
