Before 3.59.0, a freelancer might have managed their Site Manager entries—the list of servers they access—across three different computers. Keeping those lists in sync was a nightmare.
11. Recommendations and mitigations
- Do not store plaintext passwords; prefer manual entry or use key-based SFTP where possible.
- Encrypt the portable package or store on encrypted media (e.g., VeraCrypt) when carrying sensitive credentials.
- After use on untrusted machines, delete temporary files and verify local system integrity.
- Prefer modern FileZilla releases with up-to-date TLS/SSH libraries; if portability is required, recreate a portable package using current stable binaries and verified libraries.
- Where available, integrate with platform-provided secure credential stores rather than saving creds to portable files.
